How do over-the-counter whitening strips and gels work?

ANSWER

Whitening gels are clear, peroxide-based gels applied with a small brush directly to the surface of your teeth. Instructions vary depending on the strength of the peroxide. Follow the directions on the product carefully. Initial results are seen in a few days and final results are sustained for about four months.

Whitening strips are very thin, virtually invisible strips that are coated with a peroxide-based whitening gel. The strips should be applied according to the instructions on the label. Initial results are seen in a few days and final results are sustained for about four months.
