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).
Gum graft also called soft tissue graft is a surgical periodontal procedure in which tissue is taken from the palate or another source area in the mouth and added to an area where the tooth roots have become exposed due to gums recession caused by periodontal disease or other reasons.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.
