What is teeth whitening?

Teeth whitening is a cosmetic dental procedure that is used to brighten and whiten a person’s smile. Throughout time, teeth can get discolored or stained for a number of causes, including smoking, drinking red wine, drinking coffee, and drinking tea. Bleaching agents like hydrogen peroxide or carbamide are used to dissolve and remove stains from the dentin and enamel layers of the teeth in order to whiten them. This technique effectively lightens the teeth’s hue, making the smile look brighter and more appealing. Teeth whitening can be done professionally at dental offices or at home using kits and over-the-counter products, depending on the needs and preferences of the patient.
