Teeth whitening is a non-invasive cosmetic procedure to lighten teeth and remove stains, improving overall smile brightness.
A whitening gel, often activated by light or laser, is applied to the teeth. It penetrates enamel to break down stains from food, drinks, or smoking.
Sessions typically last 30 to 60 minutes. In-office treatments offer faster results than at-home kits. Techniques vary from laser-assisted whitening to custom tray applications.
Some may experience temporary sensitivity. Results can last several months with proper care. Follow-up treatments may be needed for maintenance.
