words from eye tooth to eye tooth. The logic in covering the

front six is that they are all you see.

Depending on the product, they are worn for 30 minutes twice

each day and for seven to fourteen days in duration.

The strips typically come with pre-applied hydrogen peroxide at a 6%

level for the fourteen day treatment. The percentage of peroxide is

increased to 10% for the seven day duration.

Tooth whitening strips are one of the more popular ways to perform

tooth whitening at home. It is both effective and inexpensive.
