If you're after a professional-level teeth whitening experience at home, Smile Brilliant delivers with custom-fitted trays, an option for those with sensitive teeth, and a powerful 22% carbamide peroxide gel. Unlike one-size-fits-all kits, this system ensures even coverage, though you'll need to take the extra step of creating your molds and sending them in for processing. Duration times range from 45 minutes to 3 hours, with best results after 7-14 applications. While the $149 to $189 price tag is higher than some alternatives, Smile Brilliant offers free shipping, a 45-day money-back guarantee, and an affordable $35 tray replacement program. Despite a "B+” BBB rating due to a handful of complaints, Smile Brilliant customers largely rave about their results. If you want a teeth whitener that fits like a glove, this is an excellent choice.

Glowfinity Review 3 Star Rating

Glowfinity

3 Star Rating
  • 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 offers an affordable teeth whitening system with gel-filled trays and an LED light, promising up to 8 shades of improvement in just a week. At $24.99 for 22 applications (plus desensitization gel), it looks like a great deal - especially since it's identical to one of our highest-rated whitening systems. While Glowfinity delivers the same whitening process, it doesn't yet have the same reputation, with fewer customer reviews and no BBB rating. Plus, minor oversights in their product descriptions and a less straightforward refund process make it feel a little less polished. If you're looking for budget-friendly whitening, this kit should still get the job done, but we'd recommend its sister brand instead for a more reliable experience.

What is the Best Way to Whiten Your Teeth?

A bright, white smile can make a big difference in your confidence, and with so many over-the-counter teeth whitening options available, you don't have to visit a dentist to achieve it. From whitening strips to LED kits, there's a product for nearly every budget and lifestyle. But with all the choices out there, how do you know which one is right for you?

Understanding the different methods, their effectiveness, and key features - like customized trays - can help you get the best results. Most at-home teeth whiteners use either hydrogen peroxide or carbamide peroxide as the active ingredient. These bleaching agents break down stains on your enamel, lifting discoloration caused by coffee, tea, wine, smoking, or just the natural aging process.

Teeth Whitener FAQ

Many people have stains on their teeth from coffee, cola, and even just day-to-day foods. Most teeth whiteners work by combining oxygen from the air and carbon in the dentin layer of the teeth, which breaks apart any colored molecules still stuck to the teeth (and which aren't removed by regular dental cleanings). Some teeth whitening systems use a whitening gel in combination with an LED light appliance for increased effectiveness, while others only use topical application of liquids or strips.
The process itself usually takes anywhere from a few minutes to an hour, depending on which system you choose. How long will it take to see a whiter smile? Some teeth whiteners produce noticeably brighter teeth within one or two applications, while others take a week or more of regular applications.
Teeth whitening can result in sensitivity in the teeth and gums. If you're experiencing sensitivity, you can shorten your time during each application or use the product less often than recommended. There are also special toothpastes that can ease sensitivity. But, the whitening process itself is rarely painful, no matter which method you choose.
It is possible for teeth whiteners to damage tooth enamel when not used properly. However, if you follow the manufacturer's directions carefully, there should be no risk to your teeth. (In other words, don't try to whiten your teeth faster than recommended!)
Not much! Most in-office teeth whiteners use the same solutions (hydrogen peroxide, carbamide peroxide) and send you home with trays to use for maintenance that are exactly like what you'd buy to use on your own in the first place. Yes, having your teeth whitened at the dentist's office gives you the reassurance that you're not overdoing it, but you're paying a lot more for it too.
That depends on you! If you avoid smoking and teeth-staining foods and drinks (like coffee and blueberries!), use a straw whenever possible, and keep up with your regular dental cleanings, your pearly-white smile should last a long time - several months to a year or more.
At-home teeth whitening systems are surprisingly affordable! Some of the most effective products cost less than $50 for 20 applications (and you'd pay four times that much for a single in-office whitening application from your dentist).
Most manufacturers of teeth whitening products offer a satisfaction guarantee of at least 30 days, giving you plenty of time to try it out and see if you get results. Just be aware that some products' fine print says that you can only get a refund if the product is unused (not very helpful, we know).

Continued from above...

Some products rely solely on these ingredients, while others add LED lights to supposedly speed up the process (though the jury is out on whether these lights provide a noticeable difference). The next thing to know is how these whiteners are applied to your teeth.

One of the most well-known application methods is whitening strips. These thin, flexible strips are coated with a whitening gel and adhere directly to your teeth. They're one of the most affordable and widely available options, but since they're a one-size-fits-all solution, they might not reach every part of your teeth evenly.

You may also consider whitening toothpaste or rinses. These are the least expensive options, using mild abrasives or low concentrations of peroxide to gradually whiten over time. However, they won't give you dramatic results.

The most common approach we've found for DIY teeth whitening are gel and tray systems. These kits use a peroxide-based gel applied to a tray that fits over your teeth. Some are pre-formed, while others allow for a more custom fit. While the ready-made trays are often less expensive, a major downside of one-size-fits-all whitening trays is that they don't conform perfectly to your teeth. This can lead to uneven whitening, wasted gel, or even gum irritation if the whitening solution seeps out. If you already use a retainer or a clear aligner (like Invisalign), you might be able to use it with a whitening gel instead of buying a separate system. A custom-fit tray holds the gel against all the surfaces of your teeth, ensuring a more even and efficient whitening process.

Ready to get your brightest, whitest smile but not sure where to start? Here are a few ways you can decide which option will be the best for you:

  • Effectiveness. Does the product contain a high enough concentration of peroxide for noticeable results? What do users say about how quickly they saw their teeth get whiter?
  • Comfort. Is the formula gentle enough to avoid gum irritation or sensitivity? How often do customers say that they needed to take a break from using the teeth whiteners because their teeth started to feel sensitive (especially to hot/cold foods and drinks)?
  • Customization. Does it include a moldable tray or work with an existing retainer? Or is it a one-size-fits-all approach?
  • Convenience. How long does each session take, and how many are required? Will the system disrupt your daily routine or fit right in?
  • Price vs. value. Are you getting professional-level results? Will you need to buy more than one teeth whitener kit to get the smile you want?

Teeth whitening can be an easy and affordable way to boost your smile, but choosing the right product makes all the difference. To help you get the best results, the experts at Top Consumer Reviews have reviewed and ranked some of today's most popular teeth whiteners. With the right approach, you can easily get a noticeably whiter smile too!
