If you want to know the truth, yes, Crest Whitestrips do work. They can make your teeth look whiter because of a gel that is spread along the strip and placed onto the surface of your teeth. This substance contains hydrogen peroxide or carbamide peroxide and works to penetrate the tooth enamel to remove stains.

Depending on the specific Crest 3D White Whitestrips product chosen, strips should be applied daily for anywhere from 10 to 20 consecutive days. The packaging instructions for the particular version of the product being used should be followed. Some improvement may be seen after only 3 days.
