Dental whitening is a dental procedure designed to lighten and improve the color of teeth. Using chemical products, usually hydrogen peroxide or carbamide peroxide, dental whitening dissolves stains and discolorations on the surface of the tooth enamel. This treatment can be performed in the dental office or at home using a whitening kit provided by the dentist. The goal is to achieve whiter and brighter teeth, which can significantly enhance the aesthetic appearance of the smile.
