Crest Whitestrips Dental Whitening System, 56 Strips

Crest Whitestrips are the easy way to get whiter teeth in just 2 weeks. These thin, flexible strips conform to the shape of your teeth, and are coated with a gel that contains hydrogen peroxide, the same enamel-safe ingredient used by dentists for teeth whitening. Wear Crest Whitestrips just 30 minutes, twice a day. Simply place the gel side of each strip against your front teeth and fold the rest of the strip behind your teeth to keep it in place. In two weeks you will have noticeably whiter teeth. New clinical results prove whiter teeth for 12 months. Each box contains 56 strips: 28 for upper teeth, 28 for lower teeth. The secret to a whiter smile is in the strip - Guaranteed.
