Works really well for whitening teeth in a short period of time. It does make your teeth a little sensitive afterwards though.

Okay these definitely work!! Only downfall is that they made my teeth overly sensitive. It doesn't taste great but it works!

Pricey but worth every penny. Extremely effective. Works quickly. Keeps my smile bright despite my love of coffee.

Works great over time! I saw really good results after 2 weeks of using! I wish the price was a little lower, but overall a great product.

My FAVORITE teeth whitening product! I can't use this every day because my teeth are sensitive. The price is pretty high but it WORKS!

Very fast, very easy to use, definitely effective. This product doesn't cost too much and the results are well worth it

Definitely the best teeth whitener I've used. pretty pricey but so worth it. Every other brand I've used has been nothing compared to crest

These are easy to use and work great. I could tell the difference in the color of my teeth after two uses.

These are great! I definitely noticed whiter teeth after using a few times. The only thing was that I had tooth sensitivity.

Seriously, these are the best whitening products I've ever used. They are worth every penny and will not disappoint.
