Weirdly, this didn't work as well for me as the regular Crest white strips. I didn't really notice a difference when I used it. It didn't hurt my teeth like the original strips, but it didn't give the same results either.

These work so good it's not funny! Every now and then I will put one in just to stay on top of it and I love it. However, if you have sensitive teeth this is not for you unless you space out your whitening sessions.

I love using these! I had braces when I was in middle school and my teeth were not cute when I got them taken off. I bought some of these and I still use them today because they are such a good product.

these are surprisingly good! they're a little uncomfortable when you first wear them, but even after one use you can see that your teeth are slightly more white. with regular use, i feel like you'd be able to see a big difference in your teeth.

I am unsure if I love or hate it. It did whiten my teeth however it hurt my teeth. My teeth are sensitive and it hurt for 3 days. I would not buy again..

I LOVE my crest whitening strips! I get compliments all the time on how white my teeth are! I've tried other products and nothing ever compares! I will always be a crest fan!

These are amazing! My teeth appeared to by whiter after the first use which was awesome. They did feel like they were burning my teeth a little. I have sensitive teeth, so the ingredients were a little bothersome. Overall a great product.

I really loved the Crest Whitestrips! They are very effective and leave my teeth noticeably white. I do have sensitive teeth, so I had to go longer in between uses, but other than that i had great results!

i have extremely sensitive teeth and these do not affect them at all! i've tried many whitening products and all leave my gums sensitive or burning but not these.

I love these whitening kits they work well! One issue I have had with these are it makes you slobber a lot while in your mouth, but works well on teeth!
