These Crest 3D whitening strips are seriously effective! I noticed a difference after just a few uses—my teeth looked brighter and cleaner without any harsh sensitivity. They stick well and stay in place, which makes it easy to go about my day while using them. The results feel professional without the expensive price tag. Definitely a simple and convenient way to freshen up your smile at home!

The strips work great!

Size: 40 Count (Pack of 1)

It's a great product that works. I left the strips on for 2 hours. And my teeth were so white, I decided not to use the light. I drink 3-4 cups of strong coffee everyday, and they are still really white (after one application over two weeks ago). My gums were a little sensitive after 2 hours, but that only lasted a few hours after usage. Just be aware if you leave on more than 60 minutes. Then brush and rinse really good. I use their "brilliance" tooth paste as well.

DOOOO IT (see before & after pics)

Size: 40 Count (Pack of 1), Size: 40 Count (Pack of 1)

My dentist actually recommended this in contrast to the products offered in office! So I had to try. I was especially interested in a whitening system that would not sacrifice effectiveness for gum sensitivity. Not only could I see instant improvement, but I had no gum irritation whatsoever, not even next day. So that's the two big things that exceeded expectation. A few drawbacks though - (1) Instructions were unclear as to how long to leave the light on, & I didn't realize until after mixed Internet recommendations & testing it out blindly that it automatically times out after a few minutes; (2) the product unfortunately outlasts the light's battery life, so I had to find a $16 replacement LED on Ebay, & (3) the adhesive will strip your dental work fyi. Not cool, but still overall beneficial as a whitener & hundreds cheaper than true, professional whitening. BTW this before and after were taken within a month of each other.
