Love these. They really help maintain whiteness of my teeth. Back then the formulation would make my teeth sensitive but for some reason now it doesn’t. Easily accessible compared to other brands. At every drug store.

I really love crest white strips over any other brand. They’re@much more comfortable and I can see results fast. I like to follow up with their whitening toothpaste to keep up.

Been using this product for 5 years now. Only use it once a year because if teeth sensitivity. Does excellent job and makes my teeth super white. Leaves my teeth sensitive for a few days but the results are worth it

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.

Still using and waiting for results! I think that in order to see results it has to be used completely! I have heard my teeth are whiter so I think it is working. Can be a little pricey but cheaper than professionally whitened.

Crest 3D Whitestrips are the best...I've been using them for a few months now, and my teeth are beautiful... I receive compliments from my students every week!

These whitestrips didn’t work as well as I thought they would and made my teeth feel weak. They did help a little but not much. I’m a first time user to this product and not sure myself if I’d purchase it again.

I have used this product many times and it works extremely well. I always notice a difference after the first treatment. I have had to cut back lately because they have become so expensive. I am a single parent so other priorities come first.

absolutely work! if daily brushing and flossing isn’t keeping your teeth white, this product really will. It can be uncomfortable at first because of the band and how the product activated on your teeth, but you WILL see a difference!

Effective. When I started, I used a few times a week. Once I got to a shade I want, I use about once a week. Has gotten me very many compliments from people around me, without it being too much of an obnoxious difference or change.
