Teeth whitening, also called bleaching, is now a proven way to lighten dark or discoloured teeth. In the first step of the treatment, however, the exact cause of the discolouration has to be determined, since not all tooth stains can be successfully lightened.
In principle, endodontically treated (i.e. nerve-dead) teeth as well as “living” teeth can be lightened without long-term damage and without loss of substance. This treatment method is best suited for teeth that do not have large fillings and have a good position and shape.
The result is compelling and usually lasts up to three years. Subsequently, the bleaching process may be repeated as needed.
