I bought this one almost a month ago and have used 22 treatments. My teeth color still stay the same, no sign of brighter smile. I will try the remaining treatments and update.

For the past 3 months I've been using this toothpaste. its absolutely the best. my teeth look and feel healthy, And to mention the whiteness of my teeth. every time I smile my teeth shine bright like a diamond!!

Use to maintain my pearly whites, and am constantly complimented by my dentist(s), as I prefer a natural tone of white, than pure white color. They ask if I brush my teeth often to maintain... Flattering for my dentist to not even be able to tell!

[This review was collected as part of a promotion.] Very effective. Great value. Comfortable when using. Doesn’t make my teeth sensitive. Packaging is a durable box. Definitely try this brand of whitening products

These work just as well as a professional whitening... Easy and worth the work! Only negative thing I have to say about them is that my teeth have gotten more sensitive.

[This review was collected as part of a promotion.] I personally love using crest teeth whitening. i’ve been using it for years and I feel like there has definitely been some difference. I would recommend

I really loved the Crest 3D products. I could tell a difference in the color of my teeth in just one use. I would recommend this product to anyone. Great Product and worth every penny!

Really good. Just finished 5 days. It really whitens significantly every day. It was a great purchase and I like that it is 20 days then 1x a month to maintain for a year.

I love the white strips..however the last two boxes I bought have no white strips on the sheet...I would like to get what I pay for...the second box had more missing...I would like to be compensated for the two boxes..

I couldn't be more excited to say that the whitestrips have made my teeth and amazing vibrant white. I have always had off colored teeth which bothered me but now I have the smile i've always wanted.
