A gingivectomy is a surgical procedure in which a periodontist or oral surgeon excises a portion of the gingival tissue to eliminate diseased gum, reduce periodontal pocket depth, or correct pathological overgrowth. It is one of the most established techniques in periodontal surgery, with a clinical history spanning more than a century.

Clinical Significance

When non-surgical interventions such as scaling and root planing fail to resolve persistent periodontal pockets, a gingivectomy provides direct access to subgingival calculus and infected tissue that instruments cannot adequately reach. Removing the compromised gingiva allows the remaining healthy tissue to reattach at a shallower, more maintainable level. The procedure is also closely related to crown lengthening, where gingival tissue is removed to expose sufficient tooth structure for a restoration or prosthetic crown.

Common Indications

• Chronic periodontitis with deep pockets unresponsive to conservative therapy
• Gingival hyperplasia secondary to medications such as calcium channel blockers or phenytoin, hormonal changes, or hereditary conditions
• Exposure of adequate tooth structure for restorative or prosthetic purposes
• Removal of localized gingival abscesses or fibrotic enlargements
• Cosmetic recontouring to address excessive gingival display, sometimes called a gummy smile

Procedure Overview

The procedure is performed under local anesthesia. The clinician first marks the base of each periodontal pocket using a pocket-marking forceps, creating bleeding points that serve as an incision guide. A periodontal knife, electrosurgical unit, or dental laser is then used to excise the tissue along this line. Root surfaces and the underlying alveolar bone are debrided and smoothed before a periodontal dressing is placed to protect the surgical site during early healing.

Recovery and Outcomes

Mild to moderate discomfort is expected for several days and is typically managed with over-the-counter analgesics. Soft-tissue healing is generally complete within two to four weeks, though full maturation of the periodontium may take several months. Long-term success depends on consistent post-operative oral hygiene and regular professional maintenance to prevent disease recurrence.

When selected for the right clinical indications, a gingivectomy is a highly predictable procedure that restores periodontal health and creates conditions that support tooth retention for years to come.
