Teeth whitening is a cosmetic dental treatment that helps remove stains and discoloration from the surface of the teeth, making them appear brighter and more radiant. It can be done in a dental office or at home using various products, such as whitening strips, gels, or trays. The process typically involves the use of hydrogen peroxide or carbamide peroxide, which break down stains caused by food, drinks, smoking, or aging. In-office treatments are usually faster and more powerful, while at-home treatments are convenient and more gradual. Teeth whitening is safe when done correctly, though results can vary, and not all types of discoloration may be fully removed. It’s important to consult with a dentist before whitening to ensure it’s the right option for your teeth.
