How is gum graft surgery performed? During gum grafting surgery, a periodontist will commonly take connective tissue from the roof of the mouth (palate) and suture it to the affected gumline. This allows more tissue to grow and close the exposed root surface (gum recession).
Soft Tissue Grafting. The crown of a tooth is that part that is above the gums. Sometimes more of the tooth below the gums must be exposed to fill a cavity near the gumline or place a new crown on a broken tooth. Crown lengthening provides more tooth structure for this to to be done. This ensures that the restoration or crown procedure is successful and prevents gum irritation. Procedure: The periodontist administers a local anesthetic and gently recontours excess gum and bone tissue to expose more of your natural tooth.
