Crest is my go to teeth whitening system. I use them once a year. They are true to their promise- they whiten you're teeth quickly! Sometimes my teeth are a little sensitive after whitening but that is normal. Will use again and again.

I have been whitening my teeth on and off for 20 hrs now. I started with crest white strips I. High school, used a lot of different things, even professional whitening and Crest white strips does the job the best.

These are great for a quick refresh and for a complete do over. They take yellow, stained teeth to pearly white in about a week or so. I use them every other day for about 10 minutes and my teeth have never looked better.

I love this whitening strips. Will make your teeth white. Very effective. I hope they make it mre affordable so everyone who wants to white their teeth at home can try it.

It took me a long time to bite the bullet and buy Whitestrips, but dang, they really do work. I don't have tooth sensitivity so I don't know if they might bother people, but they don't bother me. Definitely worth it ahead of a special event.

These are highly effective. I would definitely recommend using them if you want whiter teeth; however, my teeth are always extremely sensitive after use.

I like this product and have used it for the past five years. The ones I have purchased lately, the strips stick and when I try to peel the strip from backing they stick together.

These are the only at home whitening strips that I have tried and they work really well! The only negative is that they sometimes make my teeth feel a little sensitive after using them but that may not be the case for everyone.

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

I was hesitant to try this because I'd heard bad things about other kinds of whitening brands however this was a great experience for me! Very easy to do and was very happy with my newly whitened teeth.
