Teeth whitening strip

Teeth whitening strips are thin, flexible pieces of plastic coated with a peroxide-based whitening gel that are designed to brighten the color of your teeth by removing surface stains and light discoloration. They are typically applied directly to the front surface of the upper and lower teeth and worn for a specified period, usually between 10 to 30 minutes per session, depending on the brand and strength. The active ingredients, commonly hydrogen peroxide or carbamide peroxide, penetrate the enamel to break down stains caused by food, drinks, smoking, or aging. These strips are popular because they are easy to use, affordable, and can be applied at home without professional supervision. With consistent use over several days or weeks, they can gradually lighten teeth by a few shades, although results may vary based on individual dental conditions and habits.
