Gingivectomy is a dental procedure in which a dentist or oral surgeon cuts away part of the gums in the mouth (the gingiva).
It is the oldest surgical approach in periodontal therapy and is usually done for improvement of aesthetics or prognosis of teeth.
By removing the pocket wall, gingivectomy provides visibility and accessibility for complete calculus removal and thorough smoothing of the roots, creating a favourable environment for gingival healing and restoration of a physiologic gingival contour. The procedure may also be carried out so that access to sub-gingival caries or crown margins is allowed. A common aesthetic reason for gingivectomy is a gummy smile due to gingival overgrowth.
