Careful not to use too much, while they whiten the enamel can become destroyed through everyday prolonged use. I do love them though always have worked well.

Noticed an improvement in whitening after 2 applications. I have sensitive teeth and gums so I did have to space out applications more than what was suggested

I love crest white strips! Personally i can’t do them everyday like the instructions say because my teeth are sensitive, but even using them once or twice a week and I can still see the difference. They are the only white strips I will buy

Great for getting your teeth there whitest with minimal effort. My teeth are not too stained but these always take me back to paper white! Could be longer because they don’t cover all your teeth just the ones that show in the front.

Ok so the new design of these strips are awesome. They actually stay on really well. Plus my teeth are so white using them and cheaper than whitening sessions.

I’ve been using these strips since I was in high school. They work super well and you don’t even need to do the full box consecutively, the only downside is they can make your teeth pretty sensitive

I've been using these for years. As a coffee drinking smoker, these are amazing for my teeth!! I was shocked that anything could take the stain off. But the 3D White Whitestrip Professional Effects did the job! This is all I use!

It didn't work as well as I've been hearing it does. I'm two strips away from completing the entire kit, but my teeth aren't exactly white? I thought it might be expired, but it wasn't. I'm not sure why it didn't work for me...

It's one of those puchases where I asked myself, "why didn't you try this earlier"? I have 15 more treatments and very pleased with the results so far. I hope you experience the same

I used this product all the time! I don’t anymore because it started making my teeth weak and extremely sensitive to cold and hot things I ate or drank
