(b) Crown lengthening procedures
Frequently, the restoration of teeth with extensive decay or fractures, requires surgical exposure of healthy tooth substance. In such cases, a simple surgical procedure is carried out under local anaesthesia, involving recontouring of the gums and bone around the tooth.
In some cases, patients are unhappy with the appearance of their gums, especially in the anterior areas of the upper jaw, where the gums may cover part of the clinical crowns of the teeth, thus resulting in the so-called "gummy smile". Is such cases, the teeth appear shorter than they actually are. This problem is easily resolved by crown lengthening surgery.
