Do at-home teeth whitening methods work?

Commercially available teeth-whitening pastes, strips, and gels can reduce superficial stains on teeth, but they are not as effective as professional whitening. Furthermore, uncontrolled use can damage tooth enamel and gums. Therefore, products for home use should always be selected with a dentist’s recommendation. The safest and most lasting results are achieved with professional whitening performed in an in-office setting.
