I noticed a difference in the first use. My teeth were way whiter and made my teeth glisten! They are a little pricey but definitely worth it!

I've used these white strips, and to be honest I have had good results. The more you use it the better, and I really recommend it.

Amazing. I love love love the way I feel when I have a beautiful white and bright smile. This is a staple part of my beauty routine. Worth the money.

Make a huge difference over time! Definitely can cause sensitivity but only if you use them too frequently

I was so excited to see the progress of the 3-D Crest white stripes. My dad says my smile is one of best features and now it's even better!

I tried whitening my teeth with raw hydrogen before, with whitening pens and gels but Crest strips are the only ones that work for me.

this isn't uncomfortable at all actually, and not to mention my dentist said himself these work as well as a whitening appointment!

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

The whitestrips teeth whitening kit is amazing if you want and fast and easy way to whitening your teeth

These work miracles!! Very great product! I was embarrassed about my smile before. Now I love to smile!
