Gum (Gingival) grafting is done to correct recession. The procedure creates a seal of the gum to the tooth, minimizing the potential for further recession, infection and caries at the tooth root. It can also protect gum tissue from being irritated by fillings or crowns that are at the base of the teeth. Oftentimes people desire this surgery to correct their gumline, resulting in a more esthetically pleasing smile. The surgery takes about an hour and is most frequently done with local anesthesia.
