Teeth whitening is one of the minimal intervention techniques. It is the simplest aesthetic technique. It is the healing process in which pigments are removed in or above the surface of the tooth making it look lighter and brighter. The techniques with which the desired result is achieved are many (whitening in the doctor's office or at home, whitening of an endodontically treated tooth, laser whitening or discs). The dentist suggests depending on the needs of an individual tooth or the whole block, the sensitivity of the teeth and the time that the patient can spend the most appropriate technique or a combination of them.
