2025 Teeth Whitener Reviews

AuraGlow

• Price: $39.99 for 20+ applications
• Method of application: 35% carbamide peroxide gel + LED light tray
• Duration: 30 minutes, used for 1-2 weeks
• Results: Up to 10 shades whiter in 7 days
• Shipping: Free for most customers
• Refunds/returns: 60-day risk-free refund policy (contact manufacturer)
• "A+” rated by the BBB

With so many teeth whitening options out there, finding the right one can feel overwhelming. Auraglow has emerged as a popular contender in the at-home whitening market, promising professional-level results without the hefty price tag. Let's take a closer look at their teeth whitening kit to see if it lives up to the hype.

30-minute process

The process for using Auraglow's Teeth Whitening Kit is pretty straightforward. Once you've made sure the LED light is fully charged, you should brush and dry your teeth. Apply the gel to the front of the mouth tray on the top and bottom. Then, place the tray in your mouth and turn on the LED light and sit tight for 30 minutes (maybe fire up Netflix and catch up on a show?). The light will automatically turn off when the cycle is done. Don't forget to rinse the tray and your mouth when it's over.

All you need for pearly whites

The Auraglow Teeth Whitening Kit comes with everything you need to get started, priced at just $39.99 (and with free shipping for most shoppers):

• LED Accelerator Light: A rechargeable light designed to speed up the whitening process
• Whitening Gel Syringes: Two syringes containing 35% carbamide peroxide gel (20 applications total)
• Mouth Tray: A flexible silicone tray that fits comfortably in your mouth
• Charging/Storage Case: A handy case to store and charge the LED light
• USB Charging Cable: For recharging the LED light (Note: wall plug not included)

Use daily for 1-2 weeks

You'll repeat that process daily for 7-14 days, depending on how long it takes for you to see the results you're looking for (and on any sensitivity you might feel during the course of the application). Auraglow says you can expect your teeth to get up to 10 shades whiter in just a week, so you may be able to save some of the 20 included applications for future touch-ups.

Check out the compatible products

If you don't love the idea of using an LED light in your mouth for 30 minutes, you might want to check out Auraglow's other products. Those include whitening strips (similar to rival products you've probably heard of - or seen reviewed separately here), a whitening toothpaste booster, moldable trays you can use with the gel and not the light, and even a sensitivity relief serum that can make any Auraglow whitening feel a little less uncomfortable.

60-day satisfaction guarantee

Auraglow also stands out as a teeth whitener because of its 60-day money-back guarantee. If you don't get the results you hoped for, or if you develop a sensitivity that doesn't subside between applications, or for literally any other reason, you'll have no trouble getting a refund. Just reach out to Auraglow to get the process started; they even cover the return shipping costs.

Over 40,000 5-star reviews

We're happy to report that Auraglow gets an "A+” rating from the Better Business Bureau, with absolutely no complaints filed with the BBB in the last 3 years. Better yet, everywhere else we looked, this company (and its teeth whiteners) got rave reviews - even verified as legit by Fakespot. The support team is friendly and quick to respond to issues, and the reviews are positive (but just mixed enough that we trust that they're authentic). The teeth whitening kit alone has over 45,000 ratings that average 4.1 stars out of 5: users describe the oral device as very comfortable to use (and some only had to use it for 5 minutes to see results, not the full 30), though some say that the tubes of gel don't always last for the number of applications promised. Most compelling, though, are the before-and-after photos posted by Auraglow users. You'll definitely be convinced too.

Still our #1 pick

The Auraglow Teeth Whitening Kit offers a promising solution if you're seeking a brighter smile from the comfort of your own home. With its easy-to-use design, effective whitening gel, and 60-day money-back guarantee, it's a relatively risk-free way to see if it works for you. Just remember, consistency is key, and maintaining good oral hygiene habits will help you keep your smile sparkling for longer. Auraglow continues to be our most recommended teeth whitener brand.

iSmile

• Price: $24.99 for 22 applications
• Method of application: LED light, one-size-fits-all trays, 35% carbamide peroxide gel plus desensitization gel
• Duration: 10 minutes a day for 7-10 days
• Results: Up to 8 shades whiter in 7 days
• Shipping: Free for most customers
• Refunds/returns: 30-day money-back guarantee (contact manufacturer)
• "A+” rated by the BBB

Florida-based iSmile wants you to finally love your smile by making your teeth whiter than they've ever been. Their whitening kits were designed by dental experts to give you professional-level results without having to go to the dentist - or paying hundreds of dollars. You can rest assured that all of their whitening applications have been created in FDA registered facilities.

Whiter teeth in 10 minutes

iSmile uses one-size-fits-all trays that you fill with a 35% carbamide peroxide gel, then attach to an LED light. Place your teeth into the trays, turn on the light, and wait until the light turns off (in about 10 minutes). Take the trays out, give them a good rinse, and rinse your mouth with warm water. And, if you're prone to sensitive teeth, your kit comes with one multi-use syringe of desensitization/remineralization gel that can be used after your application.

See amazing results after 7-10 days

iSmile recommends using their system daily for 7-10 days, so your kit will come with enough gel to do touch-ups every so often. You should expect your teeth to be up to 8 shades whiter after just 7 applications.

Multiple rounds of whitening for under $25

And, you can't beat the price on iSmile: 22 applications for just $24.99. Plus, since most shoppers will get free shipping, that makes this teeth whitener even more affordable.

30-day satisfaction guarantee

But that's not all: iSmile is so confident that you'll get the results you want with their system, they offer a 30-day money-back guarantee. Just reach out to iSmile (800-685-7362) to request your refund if, for any reason, you don't love their teeth whitening products.

Check out the user reviews and tips

Best of all, iSmile gets a lot of buzz from happy customers, reflected by an "A+” rating from the Better Business Bureau and more than 22,000 4- and 5-star reviews. We encourage you to read through those reviews and see the before-and-afters for yourself. You'll also find some helpful hints - like using your retainers or Invisalign trays, if you have them, to get better results than with the one-size-fits-all trays that come with the iSmile kit.

Best teeth whiteners for the cost-conscious

If budget-friendliness is a top priority, iSmile is the teeth whitener we'd recommend. Although you'll have better results if you happen to have custom trays already, you'll still see plenty of progress in your smile with the ones that come with the iSmile kit. Even without the 30-day refund policy, the under-$25 price point is still crazy-affordable for teeth whitening that actually works. iSmile is one of our favorite options for getting pearly whites.

Smile Brilliant

• Price: $149 to $189
• Method of application: Custom trays with 22% carbamide peroxide whitening gel
• Duration: 45 minutes to 3 hours, used for 7-14 applications
• Results: Within 7-14 applications
• Shipping: Free on orders over $35
• Refunds/returns: 45-day money-back guarantee, plus 2-year tray replacement ($35)
• Options for those with sensitive teeth
• "B+” rated by the BBB
• In business since 2014

If you're looking to brighten your smile without breaking the bank, Smile Brilliant might just be the answer you've been searching for. Founded in 2014 in St. Louis, Missouri, this company has made a name for itself by offering professional-grade teeth whitening solutions that you can use in the comfort of your own home. Their mission? To make that dazzling, dentist-office-level smile accessible to everyone, without the hefty price tag that often comes with professional whitening applications.

Uses custom trays for a perfect fit

One of the biggest selling points of Smile Brilliant, compared with some of the teeth whiteners we evaluated, are the custom trays. You'll have a few extra steps to go through before you begin your journey to a brighter, whiter smile: namely, getting the impressions kit, mixing the putty for the molds, and sending back your impressions. It's worth it to put the time in to watch the instruction videos on Smile Brilliant's website and get those trays made, because the whitening gel will cover your teeth much better than using a one-size-fits-all(but not very well) tray offered by competitors.

Leave the trays + gel on for at least 45 minutes

Once you get your custom trays and your whitening gel (22% carbamide peroxide), get comfy because Smile Brilliant recommends that you leave the whitening trays in for at least 45 minutes to an hour, going up to 3 hours if your teeth are comfortable with it. You can go about your daily tasks, but be careful not to get any of the gel on your clothes because it can bleach. If your teeth are more sensitive, you'll need to opt for shorter sessions and consider skipping a day between applications. You may also want to use the desensitizing gel for up to 20 minutes after each session.

Number of applications depends on your habits

The brand breaks down your options by non-sensitive vs. sensitive teeth (do you typically feel a twinge when drinking hot or cold foods or in other situations?) and then by the number of applications in the package. They offer a helpful set of guidelines for helping you make the call on how many times you should use it: the T9 kits come with 27 applications (for both top and bottom teeth) and are ideal if you drink coffee, tea, or wine regularly; you're a smoker; or if you have heavily-stained teeth. The T6 kits include 18 applications and are suitable for an average person's teeth (relatively regular drinker of tea, wine, coffee). Finally, the T3 kits are for those who have whitened their teeth in the past and just need some maintenance, not regular drinkers of the aforementioned beverages, and aren't smokers. The sensitive-teeth kits are exactly the same in the number of applications. However, those packages also include desensitizing applications.

From $149 to $189

How much does Smile Brilliant cost? Expect to pay between $149 to $189 for your custom trays and your course of application ($149 for the non-sensitive T3 package, $189 for the sensitive T9 kit). The company also offers payment plans of 0% APR and 4 monthly installments; on the $189 teeth whitener kit, for example, you'd make four payments of $48/month, just slightly more expensive than paying for it upfront. Also, since shipping is free on orders of $35+ here, you won't have to factor in any delivery costs on your first kit order.

Generous 45-day refund policy

And, if you don't see the whitening results you wanted within the first 45 days, Smile Brilliant has a 100% money-back guarantee. Considering that they incurred the expense of making personalized trays for you, that refund policy is beyond generous.

Replace your trays for just $35

Having been long-time wearers of teeth-straightening trays, we know that it's not uncommon for them to break down over time (...or to get lost during a vacation...). Smile Brilliant understands that too, so they offer a 2-year tray replacement benefit for just $35. Whether your teeth whitening trays are destroyed by your dog, damaged through regular use, or simply misplaced, you can get them replaced by just submitting the request on the Smile Brilliant website and paying the fee.

Fantastic results

How about reputation? Smile Brilliant has a "B+” rating from the Better Business Bureau, held back from getting an "A” only because of 10 complaints filed with the BBB, all of which received a friendly, prompt, and appropriate response. There are lots of 5-star before-and-after reviews on the Smile Brilliant site, as well as a bunch of 4- and 5-star reviews left for the company on Google. We'd love to see some more recent feedback, though: most of the Google reviews were several years old, and the ones on the Smile Brilliant site were undated. However, the overall impression of this teeth whitener brand is very positive, with plenty of praise from customers (and the obvious results in the photos).

Excellent way to get your teeth whiter

Long story short, if you want the most bespoke, over-the-counter teeth whiteners available today, Smile Brilliant is the perfect place to start. It's one of the only options that comes with custom trays that will keep the gel right on your teeth with no gaps, has a 45-day refund policy, and provides options for people with sensitive teeth. Although the price point might be a deterrent for some (which is why it's not the #1 whitening system on our list), Smile Brilliant gets plenty of positive feedback and should deliver your brightest, whitest smile in just a few applications.

Crest 3D Whitestrips

• Price: $29.99 for 22 applications
• Method of application: Hydrogen peroxide-based strips applied to teeth
• Duration: 45 minutes, used daily for 22 days
• Results: Up to 20 shades lighter
• Shipping: Free for most customers
• Refunds/returns: Refund within 60 days if you contact the manufacturer
• "A+” rated and accredited by the BBB under Procter & Gamble

If you've been thinking about whitening your teeth but don't want to spend a fortune at the dentist, Crest 3D Whitestrips might already be on your radar. These at-home whitening strips have been around for years and are one of the most popular options for brightening your smile. But are they right for you? Let's break it down.

Gel is held on your teeth by disposable strips

Crest 3D Whitestrips are thin, flexible strips coated with a whitening gel that contains hydrogen peroxide - the same ingredient used in many professional whitening applications. You apply them directly to your teeth, and they work to lift stains caused by things like coffee, tea, wine, or just everyday life.

Go about your business during the application

Using these teeth whiteners is simple: peel the strip off its backing, press it onto your teeth, and let it sit for the recommended time (usually 45 minutes). You can wear them while doing chores, watching TV, or scrolling on your phone (though maybe skip eating or drinking anything besides water). They're definitely more convenient on-the-go than some other whitening methods like trays or LED lights. After that, you just remove them and toss them out - no rinsing required. That said, applying them can take a little practice - getting them lined up perfectly on your teeth isn't always easy at first. But once you get the hang of it, it's pretty straightforward.

Less than $30 for 22 applications

Priced at $29.99 (and with free shipping for most customers), each box of Crest 3D Whitestrips comes with 22 applications: 20 regular ones, and 2 "express” options (which are worn for a full hour). Those fast-track strips would be a great way to jump-start your brighter, whiter smile, especially if you're gearing up for something photo-worthy like a new driver's license pic or an upcoming event. You'd then use the other 20 applications every day, until you've finished up the whole box. Crest says you can expect your teeth to be 20 shades lighter by the time you're done - and lots of before-and-after photos would seem to prove that.

Results can last up to 6 months

One of the best things about Crest 3D Whitestrips is that the results tend to last a while - up to six months in many cases if you maintain good oral hygiene. Of course, if you're back to sipping coffee or red wine daily without rinsing or brushing afterward, those stains might creep back faster. Luckily, Crest offers touch-up products if you need a quick refresh down the road.

Sensitivity is a known issue

What about sensitivity? That's where things can get tricky. Some people experience tooth sensitivity or gum irritation while using Crest 3D Whitestrips. If you've ever had sensitive teeth, you might feel a little discomfort during or after each applications. The good news? The sensitivity is usually temporary and goes away once you stop using the strips.

60-day refund window

If you try Crest 3D Whitestrips and don't get the whitening results you expected (or they make your teeth more sensitive than you can tolerate), you can call the toll-free number on the back of the package (800-208-0169) within 60 days of purchase. You'll need to have your online receipt and the UPC from the package, though, so don't throw either of those out.

Best whitening method if you're on the go

Crest 3D Whitestrips aren't perfect - they won't work miracles on deeply stained teeth or on veneers/crowns/fillings -but they're an accessible option for anyone looking to brighten their smile at home. If you're willing to follow the instructions and stick with it for a couple of weeks, there's a good chance you'll be happy with the results. We give Crest 3D Whitestrips a high rating for being some of the most affordable, effective teeth whiteners on the market.

Supersmile

• Price: $40.50 for a one-month supply
• Method of application: Toothpaste + accelerator (no trays)
• Duration: 2 minutes of regular brushing, twice a day
• Results: Up to 5 shades lighter in 6 days, 9 shades whiter in 30 days
• Shipping: Free for most customers
• Refunds/returns: 30-day satisfaction guarantee (contact manufacturer)
• "A+” rated by the BBB
• In business for over 40 years

If the thought of having to hold an LED light in your mouth or stick whitening strips on your teeth makes you want to forget about getting a brighter smile altogether, Supersmile could be your best bet. This teeth whitener is used just like regular toothpaste, no trays (or gagging on nasty-tasting gel) required. The company has been around for over 40 years and offers a range of oral healthcare products, from the Zina45 sonic toothbrush to mouthwash and more.

Whitening toothpaste without abrasive ingredients

So, what makes Supersmile's toothpaste and accelerator different from any other whitening paste on your local drugstore's shelves? First off, this whitening toothpaste has no abrasives common to other products (like silica or charcoal). Supersmile is quick to point out that those abrasives do take stains off - but they take your enamel off too. Instead, Supersmile uses a proprietary peroxide called Calprox to dissolve the bio-film that bacteria, plaque, and yes, stains adhere to.

Great for sensitive teeth, but maybe not as effective

That could be a plus and a minus: many of the teeth whiteners on our list work by opening up the "pores” in your teeth to release stains. Supersmile seems to address surface-level discoloration only - but that also means that its formula shouldn't provoke any sensitivity either. If you've tried gel-based whiteners and wound up too uncomfortable to continue, this toothpaste could be the right choice for you.

Brush for two minutes, twice a day

Supersmile is extremely easy to use. You just apply the paste and the accelerator directly to a dry toothbrush and brush away for your normal two minutes (hint: that's the length of time that most electric toothbrushes run). Do that twice a day and you should see your smile get up to 5 shades lighter in the first 6 days, and up to 9 shades whiter after using it for a month.

30-day refund policy

If you're not happy with your results from using the Supersmile toothpaste, you can request a refund within 30 days of your purchase. Just reach out to the company (800-784-7645) to get the instructions for making your return and getting your money back.

Long-standing reputation for results

In general, Supersmile has the kind of reputation you'd expect from a brand that's been around for more than four decades: an "A+” rating from the Better Business Bureau, and thousands of 4- and 5-star reviews. We invite you to look through those customer comments, especially the ones that included before-and-after photos; Fakespot analyzed all of them and gave them an "A” rating for being legit. You may even get some helpful tips for using Supersmile's teeth whitening toothpaste more effectively, like combining it with the whitening mouthwash or only using a small dot (not the swoopy swirl often pictured in traditional toothpaste marketing photos).

A little on the spendy side

The only major downside for Supersmile is the cost. At $40.50 for a one-month supply, it's not the cheapest teeth whitener on our list. And, some people who've used it say that they didn't get whitening results that were superior to any of the more every day, big-brand whitening toothpastes on the market - not enough to justify the much higher cost, anyway.

Terrific alternative to trays and gels

All told, we give the whitening toothpaste/accelerator combo by Supersmile a strong rating. It's always a relief to find products from well-established brands that do what they promise, and we'll be honest: we're not the biggest fans of the gel-tray-for-10-to-60-minutes teeth whitener systems, so to have Supersmile as an effective alternative is a breath of fresh air (pun intended).

Philips DayWhite

• Price: $66.99 for 6-pack of whitening gel + 1 sensitivity relief gel
• Method of application: 14% hydrogen peroxide gel (no trays provided)
• Duration: 30 minutes per day
• Results: Optimal results within 2 weeks
• Shipping: Free for most customers
• Refunds/returns: Not accepted
• Frequently used and recommended by dentists/orthodontists

Philips DayWhite is one of the most often-used in-office teeth whitening applications, usually in conjunction with the Zoom LED system. Fortunately, if you want professional-level results without the hassles of a dentist visit, you can buy the DayWhite gel on its own and use it at home.

New, gentler formula works in 30 minutes a day

There are some pros and cons to choosing DayWhite as your teeth whitening system. First, let's talk about the upsides. Recently, Philips changed its formula from 38% carbamide peroxide to 14% hydrogen peroxide, to make it less likely for customers to experience any annoying sensitivity while using the whitening gel. You only have to use the gel for 30 minutes a day, and you should see optimal results within just two weeks of use.

Could last you for almost a year of applications

You also get plenty of product for your money. Philips DayWhite comes in various package options, but we'd recommend the 6-pack of whitening gel plus 1 tube of sensitivity relief gel that's priced at $66.99. That will give you more than enough to get maximum results over 14 days, plus extra tubes for touch-ups later on. And, most customers will qualify for free shipping.

Proven results in whiter smiles

Besides that, the results speak for themselves. Going through the before-and-after photos across hundreds of reviews, it's easy to understand why so many dentists and orthodontists recommend DayWhite. This teeth whitener really works, and the new formula has accomplished its mission of making brighter smiles feel much more comfortable while people are on the journey.

You're on your own for getting trays

Now, let's look at the downsides. For starters, Philips DayWhite is best used with a customized tray - so unless you already have Invisalign or similarly-styled retainers (after having braces or maybe a night guard), you'll have to get them somewhere else, at an additional cost.

No refunds

Next, there's no satisfaction guarantee when you're using DayWhite. If you don't get the shade difference you were expecting, or you find out a couple applications in that your teeth are still too sensitive to consistently apply the gel, you're out of luck.

30 minutes can feel like a long time

Finally, there's the application itself. DayWhite falls right in the middle of the pack with respect to duration: some rival teeth whiteners only require you to spend 10 minutes a day with trays (and often lights) in your mouth, while others (like strips) often have a 60-minute application timeframe. We've used DayWhite, and it's not the most tasty thing to have in your mouth for a half-hour; also, it's important to point out that you may want to wear your grubby clothes while you've got your trays in, because it could bleach out anywhere you accidentally dribble a bit. (But that's true for virtually all of the peroxide-based whitening options on our list.)

A solid option if you already have trays

Philips DayWhite earns an above-average rating. It's obviously effective, or it wouldn't be the in-office whitener of choice for so many dental professionals. And, the user photos show that it can deliver equally dramatic changes in shade when used at home. But, that in-home use isn't as ready-to-go right out of the box as some of the competitors on our list: you'll have to get some kind of trays if you don't have them already. And, it's not the least expensive package on the block. If you've already got Invisalign or some other retainers/trays, Philips DayWhite is a teeth whitening option we recommend - but you may still want to look at the other options on our list first.

SNOW

• Price: From $19 to $180
• Method of application: Multiple options (including whitening strips, wand, toothpaste booster, tray with/without LED light)
• Duration: Depends on selected method
• Results: Depends on selected method
• Shipping: Free on orders of $125+
• Refunds/returns: 60-day money-back guarantee
• Complimentary rewards program
• "A+” rated and accredited by the BBB
• In business since 2017

Dr. Brian Harris DDS launched the SNOW company in 2017, on a mission "to make whitening oral care accessible and uncomplicated”. All of the formulas behind their teeth whiteners are made in-house, under his supervision, and with the goal of delivering professional-level results from the comfort of your own home. And, while you may have seen SNOW products on the shelves of your local drugstore, big-box retailer, or even your favorite warehouse, the best (and most consistent) selection will always be on the brand's own website.

Lots to learn in the FAQs

In the FAQ section (and throughout the rest of the SNOW website), you'll find helpful videos showing you how to use the different types of teeth whiteners they offer. We recommend you look through those clips, not only to help you make your choice, but also to make it more likely that you'll get the pearly whites you're hoping for. And, another way to save money at SNOW is through the rewards program. We're not sure if you're automatically signed up when you make your first purchase, but you'll also find the link to join in the FAQ.

A variety of ways to whiten your teeth here

You might feel a little overwhelmed when you first start browsing the SNOW website, though. Unlike many of the teeth whiteners on our list, which focus on a single product (like whitening strips or gel/tray combos), this brand really covers them all. Let's take a look at the categories of teeth whitening options you can choose from at SNOW:

• Whitening Devices: these include the mouthpiece and gel - SNOW calls it "serum” - in a style similar to what you've probably seen elsewhere. The serum comes in a "wand”, and you apply it to the front of your teeth like painting a fence. You then use the plug-in mouthpiece for 9-30 minutes, and the mouthpiece can be cleaned with gentle soap and water. This system is used once a day for three weeks, and then SNOW recommends you do a touch-up session at least twice a week. Also, the serum comes in both regular and maximum strength; you can try each one to see if you experience any sensitivity.
• Whitening Toothpaste: these come in two varieties, Morning Frost and Midnight Mist, the latter of which includes licorice root extract and lavender oil, to fight the bacteria in your mouth while you sleep.
• Magic Powder: this powder is used as a booster for any toothpaste you're already using. Just sprinkle it on your brush (or dip your toothbrush in) and brush as usual. The recommended usage is once a day, up to four times a week, and SNOW recommends that you talk to your dentist first if you have weakened enamel or sensitive teeth.
• Magic Strips: these whitening strips may also be familiar to you (comparable with another well-known teeth whitening option on our list). The big difference with these? They dissolve completely on their own in 15-30 minutes: nothing to peel off and throw away when the application is done.

Prices range from $19 to $180

So, what's the damage to your wallet for any of the SNOW's teeth whiteners? We saw a range from $19 (Purple Whitening Toothpaste Tablets, but they were out of stock) to $180 (the Perfect Pair Bundle with two electric toothbrushes, two tubes of whitening toothpaste, and a booster whitening gel). We also spotted the Toothpaste Booster priced at $40 (and with a buy-2-get-1-free special), the DiamondSeries Teeth Whitening Starter Kit for $59, and a 3-pack (14 strips per pack) of the Purple Whitening Strips for $117.

60-day refund policy

Unless your order is at least $125, you won't get free shipping at SNOW. Any delivery costs will be calculated and displayed when you reach the checkout page. But, on a more generous note, this retailer offers a 60-day money-back satisfaction guarantee: if you're not completely happy with the quality or results of the teeth whiteners you choose here, you can get a full refund. All you have to do is either call the customer support center (888-991-2796, M-F, 6a-5p MST) or use the self-service returns portal on the SNOW website. Easy-peasy!

"A+” from the BBB...

There are thousands of reviews on the products at SNOW, but are they legit? Let's take a closer look at this company's reputation. Under the name of SNOW Cosmetics, this teeth whitening company earns an "A+” and accreditation from the Better Business Bureau. But, we're a little surprised by that perfect grade, considering how many of the complaints filed at the BBB - over 70 in the last year alone - mentioned packages that either never shipped or that arrived with items missing. One person said her box only came with a free-with-purchase promo and not the actual toothbrush she ordered.

...but lots of complaints about customer service

"The customer service here is terrible”: that's the most common complaint we found, on the BBB, Trustpilot, and beyond. Rant after rant said that weeks go by with no delivery of the teeth whitening products they ordered, and that every attempt to get help from SNOW's customer service team is a total failure. It seems that the only way that customers can get a hold of a company rep is by filing a complaint: those seem to get quick responses. But, of course, we'd prefer to see SNOW do such a good job that no one needs to jump through those hoops just to track down a missing order or to take advantage of the 60-day money-back guarantee.

Great products, but customer service needs work

We have really mixed feelings about SNOW. We love the wide range of teeth whitening products, and the 60-day money-back guarantee is extremely generous. But, with so many customers not getting the right orders, or even being repeatedly told that their subscribe-and-save items are out of stock (while still showing as available on the website), our enthusiasm for and confidence in this brand have taken a hit since our previous review. SNOW gets just an average rating this time around.

Glowfinity

• Price: $24.99 for 22 applications
• Method of application: LED light, one-size-fits-all trays, 35% carbamide peroxide gel plus desensitization gel
• Duration: 10 minutes a day for 7-10 days
• Results: Up to 8 shades whiter in 7 days
• Shipping: Free for most customers
• Refunds/returns: 30-day money-back guarantee (contact manufacturer)

Glowfinity is a newer brand in the teeth whitener space, getting your teeth lighter and brighter through gel-filled trays and an LED light. And, at a price point of $24.99 for 22 applications plus desensitization gel, it's going to get your attention. But should this be the teeth whitening system you choose? Take a look at what we found out, and choose for yourself.

A dupe of another teeth whitener on our list

If you've looked through our other reviews, you may have already noticed that Glowfinity's teeth whitening system looks exactly the same as another brand in our review, iSmile. While we didn't see anything from either company confirming that the two brands are actually the same company, the fact that both brands' addresses track to third-party mailboxes/virtual offices in Ft. Lauderdale makes us think that we're not too far off base with that idea. Plus, the wording on the products is almost identical, and both companies are DBAs: iSmile is a DBA of 720 Ventures LLC, while Glowfinity is a DBA of 296 Ventures LLC. Yep, we'd say the two are exactly the same product.

10 minutes per daily application

But, just in case you decide to roll with Glowfinity, we'll go over the teeth whitening system they offer. This product whitens your teeth with 35% carbamide peroxide gel, which you apply to two one-size-fits-all trays. Those trays plug into an LED light. You bite down (gently) into the trays, turn on the light, and it'll run for 10 minutes. When it turns off automatically, wash out your mouth with warm water and rinse the trays thoroughly.

Use for up to 10 days

You'll do one session of Glowfinity per day for up to 10 days. If you start to notice sensitivity, your kit comes with desensitization gel you can apply to make your mouth a little more comfortable. Glowfinity gives you enough of the whitening gel to cover 22 applications - plenty to get your teeth nice and white, plus some touch-ups down the road.

30-day refund policy via email request

How about the results? Like iSmile, Glowfinity says that you can see 8 shades' difference after 7 applications. If you don't, or if you're unhappy with this teeth whitener for any reason, you can get a full refund within 30 days. However, unlike the other brand with this same system, Glowfinity doesn't provide a toll-free number to reach out and make that request; instead, you'll have to email the company and wait for a response.

Reputation is newer than its sister brand's

And reputation? Glowfinity doesn't yet measure up to its sister brand: the company doesn't have its own rating with the Better Business Bureau, and while the 4.5-star average is impressive, it only spans 2400+ ratings and not the 40,000+ that iSmile has already brought in. We used Fakespot to take a deeper look at Glowfinity's reviews and didn't come up with any concerns, but the tool did point out that this is a newer company and product listing (which we had already figured out ourselves...).

Not as professional-looking

The last reason for not ranking Glowfinity as high as its sister brand is the fact that we found weird typos in the product description. For example, it said "[HYPOTHETICAL]” at the start of the usage directions - oversight or not, it didn't give us a lot of confidence to see that.

A good option, but we'd use its sister product instead

If you were drawn in by Glowfinity's low price point and reviews with before-and-after photos, we get it. After all, iSmile is one of our top-recommended teeth whitening systems, so it's logical that this brand would be pretty appealing too. However, Glowfinity doesn't quite have the same polish or reputation on its own yet. If you're sold on the idea of paying less than $25 for your teeth whitening, we'd recommend going with the better-established iSmile brand instead. But, since we know that Glowfinity uses the same gel and LED trays as its higher-ranked sister brand, we still give it a "good enough” score.

My Smile

• Price: $32.95 for 9 applications
• Method of application: 18% carbamide peroxide gel in non-custom tray + LED whitening light
• Duration: 10 minutes per application
• Results: 1-3 shades whiter after first application, up to 10 shades lighter after full course of 9 sessions
• Shipping: Free for most customers
• Refunds/returns: 30 days to request a refund or replacement on new, unused products only

MySmile isn't one of the best-known names in teeth whiteners. Although they claim to be "located in California” with products proudly made in the USA, there's definitely some "not from around these parts” wording in what you'll read in the product listing. But what about how their teeth whitening system actually works? Read on and see for yourself.

No surprises in how these whiteners work

Much of what you can expect from the MySmile teeth whitening system is standard: you'll get tubes of 18% carbamide peroxide gel, which is applied to an oral tray that goes over your teeth. However, these trays aren't customized to your bite, so you may not get quite the same cleaning (or it might take more gel to get thorough coverage).

10 minutes of LED

On the other hand, MySmile takes those trays to a novel place with an LED whitening light. The trays plug into the battery-operated base (and the batteries are included), and you just turn on the light while you bite down into the trays for a 10-minute application period.

10 shades lighter in 9 applications

And results? According to MySmile, you should see noticeable whitening of 1-3 shades with just one application, with up to 10 shades lighter after the full course of nine applications that come in your kit.

Middle-of-the-road pricing

At $32.95 for those nine applications, MySmile is neither the most nor the least expensive teeth whitening kit on our list. And, shipping is free for most people who buy MySmile; depending on where you live, you may be able to get your teeth whitening kit with no-cost same-day delivery.

Many reviews might not be legitimate

MySmile doesn't have a listing with the Better Business Bureau, so we had to base our reputation off its customer reviews. You might be excited at first when you see the 4.2-star average across more than 19,000 customer ratings - we were too. But, when we used the handy Fakespot tool to analyze those reviews, we were disappointed to see that almost 12,000 of those reviews were deemed "questionable” in terms of authenticity. Overall, MySmile's teeth whitening kit only came away with 2.5 stars and a "C” rating, based on Fakespot's analysis.

You've got better teeth whitening options out there

At the end of the day, this teeth whitening system uses roughly the same approach as most of the competitors on our list (namely, carbamide peroxide), with the addition of a somewhat gimmicky-looking LED whitening light. At $32.95 for 9 applications, it's right in the middle of the pack pricewise, so you're not going to be out an arm and a leg if you give it a try and it doesn't work the way you'd hoped (since the 30-day return window only applies if the product is unused). The potential review manipulation left us feeling a bit unhappy with this company, but if you don't find what you're looking for with the higher-ranked rivals on our list, it's not the riskiest option either.

Polar MD

• Price: $69 for 60 applications
• Method of application: Carbamide peroxide gel, one-size-fits-all tray, LED light
• Duration: 15 minutes
• Results: 12 shades lighter in 7 days, maximum results in 2-3 weeks of daily use
• Shipping: Free for most customers
• Refunds/returns: 30 days on unused products only

Polar MD is a teeth whitener designed to erase deep surface stains without any sensitivity. It uses carbamide peroxide gel (though we're not sure in what concentration: we've seen both 18% and 35% mentioned in the product literature...) with a one-size-fits-all mouthpiece and an LED light to get your smile looking whiter and brighter.

Instructions are less than clear

How do you use Polar MD to whiten your teeth? Start by brushing your teeth. After that, this company seems to be at odds with itself: the directions in the description say that you apply the whitening gel to the mouthpiece trays, but everywhere else (including the demo videos) it says to use the pens to "paint” the gel onto your teeth. (We'd recommend the latter, since the trays are one-size-fits-all and may not make contact with all of the surfaces of your teeth.) You'll have to set a timer for 15 minutes; the LED light doesn't turn off automatically. When the time is up, rinse out your mouth and the mouthpiece.

Enough whitening applications for a year

According to the company, you can expect up to 12 shades lighter teeth in just 7 days of consistent use, with maximum results after 2-3 weeks of daily use. Your kit will come with 60 applications: enough to wash-rinse-repeat (literally) several times over the course of a year.

You'll pay almost $70

But, Polar MD is priced accordingly at $69. That's nearly three times as expensive as some rival teeth whiteners on our list, but those kits usually have just 20-25 applications. At least Polar MD will have free shipping, for most customers.

Poor reputation

Polar MD is offered by LeVaye' Cosmetics, a company with a disappointing "B-” grade from the BBB. However, that not-impressive grade was for receiving just one complaint in the last three years, and it was regarding an eyelash serum also offered by LeVaye'. Unfortunately, though, the reviews for Polar MD are unenthusiastic: many customers say that the LED light's performance gets erratic after just a few uses, and some complain that the way users have to bite down into the trays makes the light turn off from the pressure of their lips.

Not very customer-centric

Plus, Polar MD doesn't seem to have a great refund policy. As far as we could tell, you only have 30 days to send back your teeth whitener kit, and it doesn't look like you're eligible if you've actually tried the product. You could reach out to LeVaye' and ask, but there's no toll-free number provided to do so. That's another disadvantage, when you compare Polar MD to its higher-ranked rivals.

A teeth whitening system we'd skip

Our overall impression of Polar MD? Sketchy. With conflicting product information and usage instructions, it doesn't exactly scream "professional teeth whitening” or "guaranteed results”. You've got a lot of options to choose from on our list, ones that have earned hundreds (or even thousands) of 5-star reviews. We'd recommend skipping Polar MD in favor of one of those higher-ranked teeth whiteners on our list.
