Where can you find the best teeth whiteners? In the past, the only way to eliminate years of coffee, wine and cigarette stains was by going to the dentist and spending a lot of money for in-office treatments. Why spend the time and the cash on expensive professional teeth whitening when the same technology - and results! - are available for in-home use?

There are several types of do-it-yourself teeth whiteners on the market today. Some use silicone trays with whitening gel, in conjunction with powerful-yet-safe LED lights that accelerate the process, leaving you with a brighter smile in just a few uses. Others consist of topical solutions that are either swabbed onto the teeth or applied with adhesive strips. The best at-home teeth whiteners are specifically formulated to avoid creating any sensitivities in your gums and teeth.

iSmile

Cost:

$48 for 22 treatments ($2.18 per use)

iSmile promises to whiten your teeth just like the $500 procedure you could get at the dentist's office: up to 8 shades whiter in 7 days. The great news is, customers say that this teeth whitener actually delivers on that promise. At the time of our review, more than 450 people had given iSmile a flawless 5-star rating.

iSmile has several differences from other teeth whiteners on the market that might appeal to you. First, the treatment length is only 10 minutes per day, and it's only recommended that you use it for a total of 10 days (unless your dentist gives you approval to use it for a longer period of time). Compared with other systems that have to be used for up to a half an hour each day, or ones that promise results after 20-30 days, iSmile gets you results in much less time. This teeth whitener also comes with a desensitization gel, to reduce the likelihood of sensitivity even further.

In most other regards, this teeth whitener is comparable to other systems we evaluated. The mint-flavored whitening gel uses 35% carbamide peroxide to make your smile lighter and brighter, and the process is accelerated by a 5-LED light device that attaches to a one-size-fits-all mouth tray. The device beeps after your 10-minute treatment is finished, to let you know it's time to take it out of your mouth.

iSmile is competitively priced at $48, or just over $2 per use. Most customers will qualify for free shipping, and some may even receive same-day delivery at no extra charge.

Their teeth whitening product is backed by a 30-day, 100% satisfaction guarantee. If you don't see the results you expected, you can get a full refund, no questions asked.

So, how well does it work? If customer feedback is any indication, iSmile produces noticeable results after just one treatment, for many people. Reading through user comments, it's easy to see that this is a teeth whitener that can be trusted to work: from pageant competitors who need to be show-ready to prospective job candidates who want their smile to leave a favorable impression, customers love how effectively and quickly iSmile makes a difference - with no side effects.

If you want one of the fastest-working teeth whiteners on the market, iSmile should be one of the first products you consider. It's easy to use and easy on the wallet, improves the whiteness of your smile in less time than competitor products, and comes with a strong satisfaction guarantee from a reputable company. iSmile is an excellent choice among at-home teeth whiteners.

Crest Whitestrips

CREST WHITESTRIPS

Cost:

$44.99 for 22 treatments ($2.25 per use)

When it comes to DIY home teeth whiteners, Crest Whitestrips was probably the first name on the market. According to the manufacturer, this product can remove 14 years of teeth stains in just 22 days.

Crest Whitestrips uses an adhesive, filmy type of applicator to stick to your teeth. Unlike many whitening systems that use trays and lights, you can go about your day while you have a Whitestrip on your teeth: talk, work, even drink water as usual. That's a huge plus if you want to use this whitener during your commute, while running errands, or even just getting things done around the house. You'll apply the strips to the front of your upper and lower teeth, and leave them on for 30 minutes.

Active ingredients include PVP, PEG-8, Hydrogen Peroxide, Acrylates Copolymer, Sodium Hydroxide, Sodium Saccharin, Glycerin and Carbomer. Note that Crest Whitestrips aren't made with carbamide peroxide: the most common ingredient in other teeth whiteners we evaluated.

This kit comes with enough strips for 22 treatments, plus a bonus of 1-hour Express Whitestrips (which give you noticeable results after one treatment, but you have to leave them on for a full 60 minutes, not 30 minutes like the regular treatments). You should expect to pay just under $45 for the kit, or roughly $2.25 per use.

A common complaint with teeth whiteners that use strips is that the teeth stay discolored in the crevices between the teeth - only the surfaces get lighter. Customer reviews of Crest Whitestrips confirm that to be the case. Comments also frequently mentioned tooth and gum sensitivity, with many people describing a burning sensation over the 30 minutes needed to keep the strips in place. You may need to use a toothpaste specifically designed for sensitive teeth. Other people said that the strips don't stay in place very well. When we used Crest Whitestrips, we found the taste to be off-putting and had a hard time leaving the strips on for the required half-hour timeframe.

But, for some people Crest Whitestrips does the job. Looking at customer photos, it's easy to see a difference in the whiteness of their smiles. So, if you like the idea of being able to go about your day while your teeth whitening system does its thing, or if you're allergic to the ingredients used by other whiteners, Crest Whitestrips could be the right fit for you. It's affordable, tested over many years, and backed by a well-known company. Just watch out for any developing irritation, and consider having some sensitive-teeth toothpaste on hand just in case.

Best of all, it's easy and affordable to shop for teeth whitening systems online. Customers appreciate being able to see before-and-after photos from real users, as well as the convenience of getting the kit and any necessary refills with just a few clicks of a mouse.

As you consider the various teeth whiteners available for purchase, how can you tell which one is right for you? Here are several handy criteria that can guide your decision:

  • Ingredients. Many teeth whiteners use carbamide peroxide, while others use hydrogen peroxide or proprietary formulas. Do you have any sensitivities to the ingredients used by the teeth whitening system you're considering? Your dentist may be able to help you answer that question.
  • Convenience. Do you have 10-30 minutes to spend with a device between your teeth each day? Or do you need something that you can apply and go about your day? Will you be able to stick to the treatment schedule for as long as the manufacturer recommends, or do you need something designed to be used for just a few days at a time?
  • Effectiveness. What do actual users say about the results of the teeth whitener? Can you see photos from real people showing a whiter smile? How long will it take to see whiter teeth for the average person?
  • Price. Home teeth whitening is always more affordable than having it done at the dentist's office or the spa, but prices still vary among retailers for DIY treatment systems. Will you get a good value for what you spend? How much will you pay per use?

TopConsumerReviews.com has reviewed and ranked the best teeth whiteners available today. We hope this information helps you find the right whitening system to give you the happy, white-and-bright smile you've been dreaming of!
