Dental bleaching, also known as teeth whitening, is a cosmetic dental procedure that involves the use of various bleaching agents to remove or reduce stains and discoloration from the surface of teeth. The procedure aims to brighten the teeth and improve their appearance. There are two main types of dental bleaching: in-office bleaching and at-home bleaching. In-office bleaching is performed by a dental professional and typically involves the application of a high-concentration bleaching agent to the teeth, which is activated using a special light or laser. At-home bleaching, on the other hand, involves the use of a lower-concentration bleaching gel that is applied to custom-fitted trays and worn for several hours per day over a period of one to two weeks. Dental bleaching is generally considered safe and effective, but it may not be suitable for everyone. People with sensitive teeth or gums, tooth decay, or other dental problems may not be good candidates for the procedure. It is important to consult with a dental professional before undergoing any type of dental bleaching to determine if it is appropriate for you and to discuss the potential risks and benefits.
