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

ANSWER

Whitening gels are clear, peroxide-based gels you apply to your tooth surface with a brush. Instructions vary depending on the strength of the peroxide. Whitening strips are very thin, nearly invisible strips that are coated with a peroxide-based whitening gel. Follow the instructions on the label to apply them.

With both, you might see results after a few days. The changes usually last about four months.
