Teeth whitening is a cosmetic dental procedure designed to enhance the brightness and overall appearance of a person's smile by removing stains and discoloration from the teeth. This treatment can be performed in-office by a dental professional or at home using customized whitening trays and gel. The process typically involves applying a whitening agent, such as hydrogen peroxide or carbamide peroxide, to the teeth, which penetrates the enamel to break down stains and lighten the tooth color. Teeth whitening is effective for various types of stains, including those caused by food, beverages, tobacco, and aging. It offers a safe and efficient way to achieve a brighter smile, boosting confidence and enhancing overall aesthetics.
