Can dental strips whiten teeth?

Tooth strips are effective in whitening teeth. If you use whitening strips for a short period of time, the strong oxidants they contain will turn your teeth from yellow to white. The concentration of hydrogen peroxide contained in whitening tooth strips is as high as 15%-35%. Long-term use can cause tooth demineralization, produce sensitive symptoms, and irritate the gums and surrounding soft tissues. After whitening, the surface of the teeth becomes rough and loses its smoothness. Exogenous pigments are easily attached to the surface of the teeth and are difficult to clean. After 3-6 months, the teeth will gradually return to their original color. Therefore, whitening tooth stickers should not be used excessively, frequently, or for a long time. You can achieve the whitening effect through long-term use of whitening toothpaste, or directly use veneers to whiten your teeth.
