Teeth whitening strips are thin plastic strips coated with a peroxide-based gel (usually hydrogen peroxide) that stick to your teeth and remove stains from the enamel surface.

They are one of the most popular at-home whitening methods because they are easy, affordable, and give visible results in days to weeks.
