I have used this for years. I have been using these whiting sets since I was 16 and stole them from my mother. I think they work great, however if you have sensitive teeth. DO NOT USE. It will cause you to rip them off.

They do not work at all it is a lying false advertising applying them daily even used 2 boxes didn't even whiten teeth by the slightest waste of time and money

I feel like they begin to work but they always leave you wanting more. I started using these around 2007 and while they have improved the strip you still must use them everyday.

Stunning! I bought 2 boxes and my teeth are so much whiter! The strips took off years of staining from coffee and tea and all other staining foods! So amazing, and I reccomend to all my family and friends and may even buy my sister a box!

I like this product! I actually saw results after a few weeks and my teeth look whiter. I will definitely get this product again and recommended it to my friends.

I like these Whitestrips from Crest! It does what it promises and I don’t think my teeth get overly sensitive afterwards. I wouldn’t use it for consecutive days though. I would definitely buy it again.

These are amazing I bought a pack of these and I love them I also let my sibling try it and now she always uses them and her teeth are cleaned and nice supper good and great way to keep teeth clean

These definitely help with whitening however leave my teeth feeling sensitive. I haven’t tried many other options so I’m not sure if it’s just this product or all whiteners.

This package does leave some sensitivity but it works amazing and I rarely use the full recommended amount of days treatments. I usually require only 3-4 days to completely clean my coffee stains off my teeth

This is a great product. I’ve been using the white strips for about a week now and I can definitely see a difference! My only issue is that my teeth were extremely sensitive after using.
