I have used this product in the past and it worked like I would have imagined I was vary happy. I stopped using it since it was a little expensive for me. I recently bought this product again and I see almost no results then before. I don't smoke or drink coffee and expected the same results as it used to provide. Maybe there something wrong thins time with the product. I do wish to have my money back or a discount to buy another box and see if there is something wrong with the product or just the one I bought.

[This review was collected as part of a promotion.] These strips do the job. I always use these whenever I have important occasions coming up. I do see my teeth brighten up after few uses. The packaging also very convenient for travel. Absolute best!

[This review was collected as part of a promotion.] These Crest 3D Whitestrips gave me a brighter, more confident smile in just a matter of days. With consistent use I noticed a gradual whitening and removal of some of the stains on my teeth. They’re easy to use either at home or on the go. I will definitely keep using to maintain my bright smile.

These strips do certainly make your teeth noticeably whiter so they do what they say they will do. In my case, they also make my teeth very sensitive after just a few applications. The sensitivity does go away within a couple days after discontinuing use. I still use them if I need a whitening boost (which I see after just one application).

I have used Crest Whitestrips for years and love them. I tend to use for a few days in a row, once a month and really appreciate the result. People ask me how I keep my teeth so white and I always tell them to look no further than Crest Whitestrips. I use them before getting in my morning shower until I finish make up and hair, so about 35 minutes - Easy peasy!! Great product, great results at a great price! Thanks Crest!

I have used Crest whitening strips for many years and I must tell you, they are the only strips that work really well as compared to the other brands out there. Also, they are a lot less expensive than the whitening procedures at a dental office. I always recommend these to my friends and family to use.

[This review was collected as part of a promotion.] I have always wanted to try these white strips but I realized they weren’t right for me. I have gone to get them professionally whitened about three times and have always experienced extreme sensitivity pain afterwards. With this product I have to wait 2-3 days until the next dose due to pain. It is simply not worth it for me. I rather get instant results one day and take pain pills instead of these week treatment. If you don’t have my issue you should give these a try they are reasonable priced and are easy to use and after using it for a week I did see my shade 1 shade brighter or at least a slight difference.

I've wasted money and time for very little effect, definitely not noticeable effects. Now I can't find who refunds this product. It's supposed to be guaranteed but no address to return the request for refund. I expected better of P&G and Crest. I want my money back to pay the dentist what I should have done to begin with. My son's wedding is in 3 weeks!! What a disappointment!

[This review was collected as part of a promotion.] After using Crest 3D Whitestrips, you can expect a whiter smile! According to the product, you'll get "10 levels whiter" teeth in 11 days. Results may vary depending on individual teeth and usage. Some people might experience increased tooth sensitivity, but the product is enamel safe and dentist-recommended 😁. I love Crest 3D Whitestrips! They're easy to use and really work. My teeth look whiter and brighter after days. Definitely recommend!

I bought these with the understanding that I would be getting 2 boxes (because that's what was shown on the site when I ordered), not a mailing box with individual packages of strips. I see they have changed the advertising now, showing how they will arrive (so at least everyone knows). It's just disappointing because they were supposed to be 2 individual gifts for 2 different people. I hope they are still effective products, that will be later determined.
