Teeth bleaching is a cosmetic dental procedure aimed at lightening the color of teeth. It typically involves the use of bleaching agents, such as hydrogen peroxide or carbamide peroxide, which penetrate the enamel to remove stains and discoloration. This process can be done at a dental office or at home using custom trays and whitening gels. The effectiveness of teeth bleaching varies based on the type of stains, the concentration of the bleaching agent, and the duration of treatment. While many people achieve a brighter smile, it is important to consult with a dentist to ensure safety and suitability for individual dental health.
