Really do whiten your teeth. But very expensive and make my teeth feel incredibly sensitive after. Breathing in cold air after using will send pain into teeth

This package does leave some sensitivity but it works amazing and I rarely use the full recommended amount of days treatments. I usually require only 3-4 days to completely clean my coffee stains off my teeth

I love this product! It's my go to whitening strip product. I think it leaves my gums slightly sensitive but I think this is the most effective product!

These are the bomb. I definitely see a difference when I use them. The only reason I deducted a star is because the edges of the bottom strip come up on the sides when using them.

Favorite whitening brand for at home whitening! I feel like even after one use I see a difference in my smile. I really like the crest 3D white strips because they also don't leave my teeth feeling sensitive!

This stuff is obviously a little expensive but it is sooo worth it! Brightened my teeth just after the first four days of using it! I've always struggled with keeping mine white no matter how much I brush. This stuff really helps!

I did see some results with this product but it's kind of annoying having those strips on teeth for a half hour, that's the only con about this item . I've used about 3 separate times , I would buy again.

These whitening strips are one of the best on the market. They effectively whiten teeth while leaving behind a clean look. These are very easy and convenient to use. I recommend these strips!
