Used one strip today! Love the quick results I get from all crest white products! They do sting a tiny bit after about 20 minutes!

These definitely made the surface of my teeth whiter, I do think that I made my teeth slightly sensitive for a short while

I use crest 3D white Strips when my teeth need whitening. I see results in one week. A little expensive but love to have them.

I used crest whitening strips ten years ago and my teeth still remain white and i have to thank using these whitening strips they are amazing !

Iv been using these for years. I always get compliments on how white my teeth are. I recommend these to everyone.

Works very quickly and efficiently. If you have a big event and need to whiten fast these are great!

I use this regularly to whiten my teeth. It makes them a bit sensitive for a few days, but that goes away and keeps my teeth white

I use the 1 hour express version and it's amazing. I always like to have them on hand because it honestly is pretty noticable immédiately!!!

Always more affordable at a Sam's Club. This stuff is just as good as the crazy expensive stuff from the dentist office.

They made my teeth really white about after a month of using these. Sloth the are a little bit on the expensive side
