Crown Lengthening is a surgical procedure performed to expose a greater amount of tooth structure for the purpose of subsequently restoring the tooth with a prosthesis. This is done by removing the gingival tissue around a tooth and after temporarily displacing the soft tissue, predictably removing a given height of alveolar bone from the circumference of the tooth operated. The goal is to improve the prosthetic forecast of a tooth, such as endodontic treatment, post and core.
