Absolutely love this product. It whitened my stained teeth in just six days and I have not yet completed the whole treatment. Highly recommend

Does the job at whitening your teeth, but if you're like me - your teeth will be sensitive for a day or two after each use

Best whitening strips! There is a clear difference after just one use! After finishing the strips you're teeth will be much whiter!

I actually use these every few days or just in the week before a big event. Even if not used in a row, they are extremely effective

These noticeably whiten teeth! I have only used about half of the pack or maybe less and my teeth are very white, more so than they were before.

If you have sensitive teeth dont get this it hurt pretty bad and had to remove them. Otherwise its probably a great product.

I swear by this. It's honestly the best whitening strips i've used. I notice a difference after using this for a week.

Takes a few times to see any results and if you have sensitive teeth it can hurt slightly. But over time it does work well.

Crest whitening strips are awesome. I can a big difference when I use and I recommend them to everyone. Even got my fiancé to start using them.

This is a classic that works every time! I usually get the smile that I want after two or three uses.
