The whitening is unreal and it is decently long lasting compared to other strips from different brands. Great purchase!!

Actual visible difference after about a week's worth of uv light brightening system. Can't imagine my life without this uv brightening system

Bling Bling!! My teeth are as white as can be. Compliments to Crest for making smile brighter than ever. 100% recommend this product!

i use them once every couple months and i get compliments everyday on how white my teeth are, this is my favorite form of whitening 100%!

Worked well for my teeth and had a bright shine. I think overall this product does exactly what it says it will do and overall is an awesome product.

I no longer use whitening strips but I used these for years, they work but I wouldn't use all the time. Maybe a once a week or every two week use

Makes my teeth feel so clean and taste great. I feel like it has helped whiten my teeth while also using the whitening strips.

these are my favorite whitening strips!! they actually work so well and don't sting on your gums like some other strips.

I used these a while ago and didn't notice a big difference in my smile. I also have heard that it can be harmful for your enamel.

this stuff made my teeth so white. crest is such a good brand. i always rebuy the whitening strips also to go with this.
