Bleaching is a common cosmetic dentistry procedure used to lighten teeth, usually to improve the appearance. This procedure is used to lighten existing tooth color or to remove stains from teeth. Bleaching can be done in a dental office or at home. In-office bleaching is the most common type of bleaching procedure. This process involves a dental professional applying a bleaching agent to the teeth, which is then activated with a special light. The activated bleaching agent penetrates the enamel of the teeth and strips away the molecules that cause discoloration. The process usually takes about an hour and may require multiple visits over several weeks. At-home bleaching is another option. This method involves a dental professional making custom trays that fit the patient’s teeth. The trays are filled with bleaching agents, which the patient then uses at home. Most at-home bleaching processes take several weeks, with the patient wearing the trays for a few hours each day. Bleaching is a safe and effective way to improve the appearance of teeth. However, it is important to note that bleaching will only lighten existing tooth color or remove surface stains. It cannot change tooth shape or size or restore decayed or damaged teeth. It is also important to note that bleaching will not whiten any existing dental restorations, such as crowns, fillings, or veneers. If the patient desires a brighter smile, these restorations will need to be replaced. In addition, bleaching can increase the sensitivity of teeth, so it is important to discuss this possibility with a dentist before beginning the process. Overall, bleaching is a safe and effective way to lighten existing tooth color and remove surface stains. However, it is important to discuss all of the risks and benefits with a dentist before beginning the procedure.
