I first received this as a sample and then i saved yo some money to buy full size. Its okay it did whiten my teeth but most of the results i had seen wasnt permanent it was effective but only temporarily if im going to biy something this expensive i would expect the results to be permanent. I like it only if it was permanent results.

These strips work wonders to my teeth! I usually leave it on for an hour and I see results when I take the strip off. I don’t love the slimy texture, but it definitely works and that’s why I use it. I use these about once a month for some white teeth.

LOVE THESE!❤️❤️❤️ they’re so great! A lot of people say they cause sensitivity, but I never have any after using these. I would suggest not brushing your teeth before applying because that may be what’s aggravating your gums causing the sensitivity.

I never expected this product to work so well! I purchased these a couple months ago and began using them. My teeth became noticely whiter in just a few days. I loved the way my new smile looked. I got so many compliments about how white and amazing my teeth look. I recommend this product to everyone wanting a whiter, sexier smile.

Loved these whitening strips. I definitely noticed a difference just after the first few days. It was quick and easy and I didn’t even use up all of the strips before I got to my desired shade of whiteness. The only thing i didn’t like is sometimes they were hard to keep on and would slip around on my teeth. Still got the job done though.

Prior to using these, I was a heavy coffee drinker. My teeth had some staining from excessive coffee consumption, as well as from tea. After the 20 treatments, I had seen noticeable results. My teeth had become a few shades lighter and most of my teeth staining had disappeared. Although I have heard a few people complain about experiencing tooth sensitivity when using these white strips, I did not find this to be an issue for me. I do believe that this is not any different from any other whitening treatment but do avoid if you are not prepared for a bit of serious discomfort. I have read that this discomfort can be mitigated by using a fluoride mouthwash and avoiding anything acidic for several hours after the treatment. Overall, I definitely recommend trying this product out!

Crest white strips are the best you can find! They are a little on the pricey side but it is so worth it! After just one use you can tell a huge difference! My dentist recommended only using once a year and use during warm weather because they do make your teeth super sensitive!

When I have an event coming up I can use Crest 3D White Professional Effects Whitestrips Teeth Whitening Strips Kit 40 Treatments Twin Pack once in a week and see a difference. These whiting strips don’t leave my teeth feeling extra sensitive. I feel they are cleaning while protecting them. I would highly recommend them and they are worth their price.

I love this product so much! I have been using these for years and always get compliments on how white my teeth are. They are easy to use and worth the price for sure. I definitely recommend for a quick boost of whitening! I will definitely continue using these.

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.
