Apply once daily for 30 minutes for 10 days
The Crest 3D Whitestrips Classic White Teeth Whitening Kit is an impressive kit. Its strips are larger than those used in some other kits, and they have a gel layer that stays in place better, making for a more comfortable whitening experience. The kit also comes with LED-light therapy, which helps reduce sensitivity. The kit's main flaw is that, like most whitening kits, it only works on a single shade at a time. But if you're looking to brighten your smile by a few shades, the Crest 3D Whitestrips Classic White Teeth Whitening Kit is a good option.
Enamel Safe and Effective
The Crest 3D Whitestrips Professional Effects Plus kit is about as easy to use as you can get. The strips are thin, flexible, and fit easily over your teeth. The whitening gel is thin, too, so it's easy to apply. The kit comes with 48 strips, which is enough for about 10 days of whitening. In our tests, the Crest 3D Whitestrips were not only whiter than regular Crest Whitestrips, but were also far less likely to cause tooth sensitivity. The Crest 3D Whitestrips Professional Effects Plus kit does give you up to 23 levels whiter in 24 days, but in our tests it was slightly more effective than the Crest 3D Whitestrips Professional Effects kit. The strips in the Professional Effects Plus kit also lasted longer than those in the Professional Effects kit, so you'll get more use out of them. The Professional Effects Plus kit comes with two free whitening mouthpieces, and if you use them as directed, they'll help you whiten even faster. The mouthpieces work well, but if you're very sensitive, you may want to stick with just using the Crest 3D Whitestrips.
Enamel Safe & Effective; Features our Advanced Seal Technology no-slip grip so strips stay put during full application time
A stellar value, Crest 3D Whitestrips are the best whitening strips we've ever tested. They claim to get your teeth 50% whiter in just 3 days, and while that's slightly longer than some other strips we tested, we were pleased with the results. The whitening gel is thick and creamy, and the strips fit securely and comfortably on your teeth. The strips only take a few minutes to apply, and with the LED accelerator light, the trays are easy to apply and to use. The strips stayed on securely, and after 20 minutes, they fell off without any mess. The whitening gel is strong enough to do the job, but it's gentle enough for everyday use. The LED light is bright but not overly so. We had no problem using it while watching TV, and while we did notice a slight tingling sensation, it went away after a few minutes. Overall, the 3D Whitestrips is a great product, and it's the best whitening strips we've tested.

The Crest 3D Whitestrips for Sensitive Teeth kit is our first pick because it uses the same whitening ingredient as dentists, has a longer treatment time than alternatives, and is less expensive than some comparable kits. The strips are thin and flexible, and they're surprisingly easy to use. The kit comes with whitening gel, a reusable tray, a whitening guide, and a whitening tip. The whitening gel is light on your teeth, and the instructions say you shouldn't feel any discomfort. The kit's tray is a bit small, but it's designed to fit well. The whitening guide has eight strips marked, so it's easy to tell when you've used enough of them. The whitening tip has a tapered tip and works well. The kit's two week treatment time is slightly longer than some alternatives. The strips have few customer reviews, but the product has earned a 4.6 out of 5 star rating on Amazon.
Safe on enamel using the same whitening ingredient as dentists
The Crest 3D Whitestrips kit is an improvement over our previous top pick, the Philips Zoom Whitening System 2, in a number of areas. The 1-hour express whiteners work faster than ever, and the package contains 32 strips, which is twice as much as the previous kit. The strips are noticeably smaller, too, and are easier to apply, thanks to Advanced Seal Technology's no-slip grip. The kit also includes 14 one-hour express whiteners, which whiten teeth more efficiently than our other picks. The gel on the strips is slightly less whitening than the gel on the Philips Whitening System 2, but it's effective, and both kits contain enough gel to whiten your teeth for 2 weeks. However, the Crest kit has less whitening power than the Philips kit, and both kits contain the same number of strips. The Crest kit has slightly inferior performance overall, but it's slightly less expensive, and it's also easier to use.

The Crest 3D Whitestrips 1 Hour Express Teeth Whitening Kit does a really good job of whitening your teeth in just one hour. The strips are very thin, so they don't cover your whole tooth, and the gel is thinner than other strips we tested. The strips are also less sticky than other strips, making them easier to put on and take off. The gel is thick and foamy, and it feels a bit uncomfortable when you first put it on, but that feeling goes away after a few minutes. The Crest 3D Whitestrips 1 Hour Express Teeth Whitening Kit takes longer than some other strips we tested to remove stains, but the results are worth it. The strips are reusable, so you can buy multiple packs and get years of use from them. The kit comes with 20 strips, which should be enough for most people, and the box comes with additional tips, so you can keep the strips from drying out.
Enamel Safe & Effective
The Crest 3D Whitestrips Vivid Plus Teeth Whitening Strips Kit is easy enough to use, but the results aren't as dramatic as with the ZOOM! Whitening Light Bright Light Up, which we like better overall. The Crest Whitestrips do provide much faster results, however, and when we used the lights together, the results were even better. The Crest Whitestrips are much easier to use than ZOOM! Whitening Lights, and you don't need any special toothpaste or drink anything special. The packaging is very nice, too. The Crest 3D Whitestrips Vivid Plus Teeth Whitening Strips Kit is also much less expensive, at $15 for a 24-count kit, compared to the $40 for the ZOOM! Light. The Crest Whitestrips Vivid Plus Teeth Whitening Strips Kit does have some drawbacks, though. The strips are very harsh on your gums, and they don't taste very good. The Crest Whitestrips Vivid Plus Teeth Whitening Strips Kit also takes much longer to work than ZOOM! Whitening Lights, and the strips don't last as long. We definitely recommend the ZOOM! Whitening Light Bright Light Up over the Crest Whitestrips Vivid Plus Teeth Whitening Strips Kit.

The Crest 3D Whitestrips Professional Effects Teeth Whitening Strips were our top pick for at-home teeth whitening. These strips use Advanced Seal Technology to eliminate over 20 years of tough set-in stains, and they remove more surface stains than some of the other strips we tested. The Crest 3D Whitestrips Professional Effects Teeth Whitening Strips use a mild abrasive to remove stains, and they contain 10% hydrogen peroxide, which dentists say is more effective than carbamide peroxide. The strips also use fluoride to strengthen tooth enamel and protect against cavities. The strips use Advanced Seal Technology, which Crest says delivers 20% more peroxide to teeth than ordinary strips. The strips have 22 strips per pack, which last about 30 days, which is longer than most strips. The Crest 3D Whitestrips Professional Effects Teeth Whitening Strips removed more stains than other strips we tested. They also removed more surface stains than strips we tested from dentist brands like Philips and Rembrandt. The Crest 3D Whitestrips Professional Effects Teeth Whitening Strips did not remove deep set-in stains, and some of our testers had to apply them more than once. The Crest 3D Whitestrips Professional Effects Teeth Whitening Strips cost less than some salon brands, but they're not cheap.
