Teeth whitening is a cosmetic dental procedure that lightens the color of teeth. It can be done in-office by a dentist or at home with over-the-counter products. In-office teeth whitening typically uses a bleaching agent that is applied to the teeth and activated with a light. At-home teeth whitening products typically use a lower concentration of bleaching agent and are applied to the teeth with a tray or strip.
The cost of teeth whitening varies depending on the method used. In-office teeth whitening typically costs more than at-home teeth whitening. However, in-office teeth whitening typically produces more dramatic results.
