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).
The gum graft procedure is performed by a periodontist under local anesthesia and it involves moving soft-tissue from another area of the mouth in order to cover the exposed tooth roots. There are three different types of soft-tissue grafts: free gingival grafts, connective-tissue grafts and pedicle grafts.he soft tissue graft, is then sutured to the existing gum tissue in the area of gum recession. This type of gum graft procedure is often used for people who naturally have very thin gum tissue around their teeth and need to have them enforced.
