Crest Whitestrips Professional Strength Supreme

Comment: These strips really work... however, they're really strong. My teeth were whiter within days, but they were also more sensitive. I had to take a three or four day break from the twice daily routine in order for my teeth to loose their sensitivity. All in all... a great product.

Comment: I was a little disappointed in the strips particulary since they were recommended by a Consumer Magazine. They don't stay on my teeth very well and I've wasted several. Make sure your teeth are really dry when you use them. My teeth do seem whiter but you can get the same effect from some of the over counter strips as well.

Comment: I met up with my friend down in Puerto Vallarta and I asked him if he had gotten Zoom bleaching done because his teeth were so white. So he told me about these strips. They came really fast in the mail. He told my by day 3 you could start seeing the difference, I started seeing it day 2. I have done the trays and different strips, these by far beat all other things I have tried.

Comment: These strips offer much stronger whitening than the regular drugstore variety. I did experience a bit of tooth sensitivity, but if you space out with a day in between that is eliminated. Found the bottom strip slips off quite a bit during the 30 minutes but still overall good whitening for the price.

Comment: The strips whitened well. If you have sensitive gums, you may need to take a few breaks during the 21 day treatment because they can be irritating.
