i have used these whitening strips since i was a freshman in high school and i am now a sophomore in college! my most asked questions are how i maintain my teeth so white and my answer is these!!

the white strips work great! buttt they make your teeth extra sensitive. every once in a while when i'm using them, it shocks a nerve in my teeth, then it hurts every time i eat/ drink something cold. i recommend them if your teeth are strong

These white strips work really well! If your teeth are very sensitive I would recommend using this because the ingredients won't make it too sensitive

I've tried a lot of whiting strips but this one I can say actually worked and didn't hurt my teeth! I have had a problem with strips hurting my teeth really bad but this was amazing!!

i've used them before and they definitely work but they would make my teeth hurt. so i haven't used them in a while,but if i had to use them again i would.

I love these white strips because my teeth actually look better than I go to a dental office and get it professionals done! People please use this which is a cheaper version! I highly recommend it!!

The Crest Professional Whitening With LIGHT brings about results very quickly after using them only once or twice. My teeth were much brighter and had people asking what I was doing different.

I love them for making my teeth very white. if you have sensitive teeth however, these may not be the ones for you. for how well they work, they are super cheap. such a great deal

I love this product and it works! But sometimes it does make my teeth very sensitive if I use them too close together (once a day before an event or something) so I have to be careful to space them out!

The whitening strips are very well developed. It is one of the only whitening products that have successfully whitened my teeth without mistake. They leave you looking professionally whitened.
