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).
3. Gingivoplasty â This type of gum surgery is used to reshape healthy gum tissue around the teeth to make them look better. If a person has tooth recession where the gum is pushed away from the tooth, a gingivoplasty can be done. A gum graft can be done where the tissue is taken from the roof of the mouth (this is called a graft) and then stitched into place on either side of the tooth that is recessed.
