Teeth whitening is a popular cosmetic dental procedure designed to lighten the color of teeth and remove stains and discoloration, resulting in a brighter and more attractive smile. The process can be performed in a dental office or at home using professional-grade products. In-office treatments often involve the application of a high-concentration bleaching agent, sometimes activated by a special light or laser, which delivers immediate and noticeable results.

At-home kits provided by dentists typically include custom-fitted trays and a lower concentration bleaching gel, allowing for gradual whitening over several days or weeks. Teeth whitening is effective against stains caused by foods, beverages, tobacco use, and aging. However, it may not be suitable for everyone, particularly those with sensitive teeth, certain dental restorations, or severe discoloration, and a dentist’s consultation is recommended to determine the best approach for achieving optimal results.
