I'm glad I tried thses #Crest3D white strips. I noticed a change in the coloration of my teeth the first week after using these strips. So I'd be buying this product from now on.

It does a really good job at whitening, it works for a fairly long time. My teeth are pretty sensitive, and it definitely rises the sensitivity, which is expected

I swear by these whitening strips. I've been using them twice a week for the past couple years and get compliments a lot on how white my teeth are. I think they work just as good as professional whitening done by a dentist

These saved my teeth. I used to be so insecure about my yellow teeth and I'm just one week they became SO white. My friends and family are always complimenting my teeth after using this product. Will definitely recommend.

These worked amazingly well. They didn't make my teeth a lot more sensitive which was sad because my teeth are already pretty sensitive. It also left a pretty gross film on my gums.

I do believe this works over time however it strips the enamel from your teeth and leaving it on for the whole time hurts your teeth. I do recommend if you use it once wait a couple weeks to do another

I've tried everything in the book to try to make my teeth whiter. My teeth aren't that sensitive so these don't hurt my teeth but I know they hurt others. They work for a period of time but after a while the white starts to fade.

I love using the crest white strips! I put them on while I'm getting ready. They make my teeth super white! You can really tell a difference after a short period of time!

I love crest white strips! I use these a couple of times a month and they keep my teeth looking pearly white! They are gentle enough on my sensitive teeth and don't cause any irritation to my gums. I definitely recommend!

Fabulous product. If you follow the instructions as directed and also be discipline and follow all the guidelines you will see a dramatic difference. This product initially made my teeth white and bright.
