Perfect way to brighten of the ole' yellow coffee teeth! I use these once a year and that's about all ya need to get the job done.

I can see results after one strip. Not the best for my sensitive teeth but it does a really good job!

My go-to product for easy, at home teeth whitening! These don't burn or cause sensitivity like a lot of the other products out there!

The whitening strips did work however it did make my teeth become sensitive so I would use them every other day or every two.

I love these. They can make your teeth sensitive but they show results very quickly and the sensitive fades away quickly

My teeth was super yellow and it made them white. It's affordable and I love them so much it helped me with my teeth so much.

Works pretty well! I usually only use these every few weeks and can usually see a difference pretty immediately.

I have used white strips for years they have always kept my teeth white and I get several comments on them being white all the time.

Crest Whitening Strips are heard of everywhere! I think you really have to keep up with them to see results though.

used these about once a day for weeks and the results were amazing! like facetune in real life. made my teeth super sensitive but i'm not surprised
