Teeth whitening treatment is a cosmetic dental procedure used to lighten the color of teeth and remove stains caused by food, drinks, smoking, or aging. The treatment uses safe bleaching agents that penetrate the enamel to break down discoloration and brighten the teeth. It can be done professionally at a dental clinic or with dentist-recommended home kits. Teeth whitening enhances smile appearance, boosts confidence, and provides quick, noticeable results when proper oral care is maintained.
