I think the work really well and they today taste bad. They really whiten your teeth #crest #crest3d

These made my teeth and gums hurt. I don't think they're safe and I wouldn't suggest more than one use if you have sensitive gums.

These are the best. I use them weekly and I always get compliments on my white teeth. They can be pricy but white teeth are worth it

These are very easy to use and produce excellent results. I use these leading up to a big event where I know I'll have my pictures taken.

I do not like these at all they are super harsh on sensitive teeth and oddly have a burning effect to it

the only white strips i've ever used. super easy to use. i've heard people say these make their teeth sensitive but i've never had that problem!

These hurt my teeth and made them sensitive. Also didn't like the taste. I don't think i saw much of s difference

I use Crest white strips every night. Really easy to apply. I've tried others but found them messy.

Perfect for that one time important whitening for wedding. Prom. Jon interview Great inexpensive professional results

3F Crest Strips are on of my favs. Convenient and almost immediate results! I'll definitely keep them near!
