Big fan of these. My teeth do get sensitive after using them so I don't use them everyday. Once a week has been good for me. Visibly whiter after a few uses.

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!

They work great! I use these occasionally every few weeks to a month at a time to help keep my teeth nice and white! They do make my teeth a little sensitive at times if I use them for too long or too often but other than that great results.

I use these whitening strips about twice a year (I love my wine and coffee lol) I definitely see s huge diference after the 4 th day and by the 7th day my teeth look like they've been whitened at a doctors office

These work great on my teeth. I will be 40 this month and by using these strips they make me look late 20's. Do not use over 15 minutes. I only use 10 minutes myself because of the sensitivity.

This product works super well! The taste isn't bad at all and Crest is a trusted brand. Had my teeth whiter in less than a week. Usually teeth whiteners leave a calcium spot on my tooth but this one, to my surprise, didn't. Would recommend!

These whitening strips are so good and last a while. They make your teeth white and stay white with consistent use. They don't cause sensitivity for me personally so I highly recommend!

Instant results even after just one use! I use these every night before bed and my teeth look so much better! They also do not make your teeth sensitive to cold foods or drinks! I love these white strips

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.

This work amazingly!!! I can't even tell you how many times a week I get complimented on my smile. These strips are definitely my “go to” to keep my smile looking fresh! I Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit
