I use these whitening strips ALL THE TIME! They work great and do not cause any sensitivity to my teeth. Unlike other whitening products, you can actually tell a difference with these!

It doesn't whiten that well, it makes my teeth hurt every single time I have tried it. It may work better for those who have less sensitive teeth though.

Whenever I actually have the discipline to use regularly, my teeth are noticeably whiter. The strips stick to your teeth without slipping like other products.

My favorite crest product as well at the 3D mouth wash. It makes me teeth glow white and if you are looking for a whitening product this is what you should use!

I love these and use them to keep my teeth white! I've never needed to get my teeth professional whitened because these do such a fabulous job. Super easy and convenient as well! I'd definitely recommend to anyone looking to whiten their teeth.

Great product and have noticed a big difference over time when using once a month or once a week however do not get the strip on your gums! Your teeth will ache and if you have sensitivity already maybe look to a whitening toothpaste only instead.

I feel like it didn't really do much for my teeth. It doesn't really change to be whiter. I also haven't used them in a while but I didn't feel the need to buy it again.

They do work! I don't like too white which looks kinda fake, this is just making my teeth at the color I like! Don't use it too long tough. You need to follow that direction.

They were slimy and wouldn't stay in my teeth very well but it didn't stop em from doing there thing!! If they wasn't so expensive I'd still be using em!

I love crest white strips. I've done several different whitening treatments but none that work as well as crest. And the light, takes it to a whole different level
