Gingivectomy is periodontal surgery that removes and reforms diseased gum tissue or other gingival buildup related to serious underlying conditions. For more chronic gingival conditions, gingivectomy is utilized after other non-surgical methods have been tried, and before gum disease has advanced enough to jeopardize the ligaments and bone supporting the teeth. Performed in a dentist's office, the surgery is primarily done one quadrant of the mouth at a time under local anesthetic. Clinical attachment levels of the gum to teeth and supporting structures determine the success of the surgery. Surgery required beyond gingivectomy involves the regeneration of attachment structures through tissue and bone grafts.

Purpose

Periodontal surgery is primarily performed to alter or eliminate the microbial factors that create periodontitis, and thereby stop the progression of the disease. Periodontal diseases comprise a number of conditions that affect the health of periodontium. The factors include a variety of microorganisms and host conditions, such as the immune system, that combine to affect the gums and, ultimately, the support of the teeth. The primary invasive factor creating disease is plaque-producing bacteria. Once the gingiva are infected by plaque-making bacteria unabated due to immuno-suppression or by oral hygiene, the bacterial conditions for periodontitis or gum infections are present. Unless the microorganisms and the pathological changes they produce on the gum are removed, the disease progresses. In the most severe cases, graft surgery may be necessary to restore tissue ligament and bone tissue destroyed by pathogens.
