They work well but my teeth are so sensitive for at least a day if not more after I use them. Worth it though!

I have used these for years and only every few weeks or sometimes months and I get compliments on my teeth all the time. They work!

Dentist review here. I have sensitive teeth and can't tolerate most whitening treatments. These do not cause me pain and the results look great.

I've used these a handful of times. They definitely make your smile whiter but they make my teeth very sensitive.

I love this product. I use the toothpaste as well. Helps me keep my teeth white and a beautiful smile

These were a great jump start on the teeth whitening process. You can definitely notice the difference but the process isn't fun.

the best whitening strips!! it doesn't hurt my teeth of my gums and afterwords they look super white!! i love it!

Not a lot of success with these. They seem to work at first but do not last lo ng. Would not recommend

I hate these. They always fall off of my teeth. They're not effective at all. I don't recommend purchasing.

I loved using these Crest Whitestrips! My dentist recommended trying them! At first, they were a bit uncomfortable, but after very easy to use!
