Bleaching and restoring endodontically treated teeth.
Internal, or "walking," bleaching has been successfully used in dentistry for many years to reverse stains associated with nonvital teeth. The procedure is predictable for color change but is not without problems. Current research has identified the cause of cervical resorption, which has been associated with internal bleaching. Second-generation esthetic bonding materials theoretically should provide an improved seal at the tooth-restorative interface, but the limited current research does not support this contention. A suggested method for internal bleaching and restoring the access cavity is presented.
