I been using the strips for about 2 weeks and I can see a litter shade on my teeth. Is not surprising because I was expecting a longer proces. The process is slow but I am getting great results.

I drink lots of coffee and smoke. My teeth were getting yellow so I tried the 3d whiting stripes and they really worked!! I think everyone should try them. Thank you!!!!

This product does work and does not cause as much sensitivity as other products. It's a good value and for most people will do exactly what they expect it to.

[This review was collected as part of a promotion.] These strips are the best I have ever tried. Teeth were 20% whiter after one use and. Will use them a lot more. They did not cause teeth sensitivity afterwards, and they were comfortable to wear.

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.] The packaging is nice and easy to fit into my bathroom. This product does cause me slight sensitivity, but it isn't long-lasting. It has helped whiten my teeth.

This has been the best product I have ever purchase, it actually functions. My teeth were a Little bit like white with yellow, now they are white. Thanks to this FABULOUS product!

After only about 2 weeks, my teeth are as white as pearls! I get compliments often and inquiries of "HOW?" All I say is.... "Crest, 3D White Whitestrips Professional Effects."

Very easy to use. Also quick to do I did in the evening. I like that I had really fast noticeable results after using. My advice take a before and after photo you will see the difference more then.

[This review was collected as part of a promotion.] I love it. It's easy to use. The taste is pleasant, the packaging is practical, and the price is good. I see results in a week. My teeth are whiter; it's real and effective.
