Teeth whitening is a cosmetic dental procedure aimed at lightening the color of teeth. It can be achieved through various methods, including over-the-counter products like whitening toothpaste and strips, as well as professional treatments offered by dentists. These methods typically use bleaching agents, such as hydrogen peroxide, to remove stains and discoloration. The effectiveness of teeth whitening can vary based on the type of stains, the method used, and individual factors like tooth sensitivity. While many people seek whiter teeth for aesthetic reasons, it is important to consult with a dental professional to ensure safe and effective treatment options.
