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.
