I honestly tried many things to whitening my teeth's I heard about the white strips and it was amazing it worked great! It's unbelievable I loved it and I can honestly reccomend it to anyone!

Only after using the second strip, I got white stains on parts of my teeth like those caused by floresis. I am extremely depressed and disappointed. My slightly yellow teeth were much better looking.

First time I tried them my teeth were yellow from coffee and tea drinking you could really tell the difference got many compliments on how white and bright my teeth were

[This review was collected as part of a promotion.] Pretty solid whitening strips. Easy to use! I didn’t notice immediate results but i definitely saw some within a week. I’d try these again to see how much whiter my teeth get.

I love these! A dentist told my mother I would never have 'white' teeth. But thanks to Crest Professional Effects I do have wonderful white teeth! I get compliments all the time on my white teeth and beautiful smile! Thank you !!!

This product worked well in some spots. But after a few days in other spots it started to wear off and need new treatments to make said spots white again! Over all very satisfied with the product. The spotting issue would be my only complaint!

I followed the directions and after 20 days I say very little change in the color of my teeth. With only 2 days left in the treatment my friend asked when I'm going to start my teeth whiting. I feel like this was a waste of my time and money.

[This review was collected as part of a promotion.] These 3D White Strips are like tiny little smile wizards—every time I use them, my teeth get a little brighter and my confidence gets a little boost. Sparkly smile, here I come!

They do not work at all it is a lying false advertising applying them daily even used 2 boxes didn't even whiten teeth by the slightest waste of time and money

These strips are Awesome!!! They amazed me by taking atleast 14 yrs of very bad stains off my front teeth. I love my new beautiful smile Thank you crest :)
