I am a huge fan! I used these whitening strips before prom and have been using the monthly touch up strips for a few years. So many friends have commented on how white and amazing my teeth look. It is worth every penny and is a great Christmas gift!

I use these strips about twice a year like clock work and I always get compliments on how white my teeth are! They are my favorite whitening product!

It was okay, it whitened my gums which was obviously a weird look- it made them actually white, but they did whiten my teeth a little bit which was awesome I just wish it was more permanent. Not sure if I would buy it again

These definitely work to lighten your teeth! I noticed after two applications that my teeth were noticeably whiter! A slight stinging sensation and tooth sensitivity when putting them on...

The best whitening product i’ve ever used. Teeth are noticeably white after only one use. Definitely worth the price, for the amazing results. Honestly any type of the Crest Whitestrips are great.

I drink several cups of black tea daily and the Crest 3D White Whitestrips Professional Effects really did remove the stains as the box said it would. I use the strips daily because I do not want to give up my tea and I want nice white teeth.

I have tried so many tooth pastes to try to whiten me teeth , I drink a lot of coffee , and it stains my teeth , I love these strips they have been the only thing that has help my teeth get an little whiter

Yes I’m sure I’ll see what you can get for supper I’ll be sure you want me a lot of things I’ll be fine I love you too sweetie I’ll talk ya ya later love you sweetie I’ll talk to ya soon sweetie I’ll see ya later love

I really liked what these made my teeth look like, however, my teeth throbbed for a while after using them both times I tried so I can’t buy them anymore. I even used them only as long as they said and it just was too strong for me.

I am on day 4 of using the white strips as indicated in the directions, and I've noticed my teeth have gotten whiter. Although, I would like some clarification as to if you're to brush before, or after strip application??
