I found some information on How Long Do I Leave The Crest Whitestrips On and gladly share it with you. Crest Whitestrips are
the easy way to get whiter teeth in just 2 weeks. All Crest Whitestrips tooth whitening kits have been shown to be safe and effective in extensive clinical and laboratory testing when used as directed. In fact, Crest Whitestrips is the #1 dentist-recommended brand of whitening system in the US. 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. Everyone's teeth are stained for different reasons. Drinking coffee and tea, aging, diet and tobacco use are a few reasons why teeth are not as white as we would like. For this reason, teeth whiten at different rates. 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. If you have more stubborn stains, it may be necessary to use a second box of
Crest Whitestrips to achieve your desired whitening results. But no matter your needs, schedule or budget, we have the Crest Whitestrips product that best suits your smile. 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.
