Depending on your oral health condition, the severity of your gum recession, and personal preferences, gum grafts can be selected from a few different sources.
Connective Tissue Grafts —This very common graft uses a piece of connective tissue taken from the roof of your mouth by creating a small flap in the skin, removing some of the tissues underneath, then reattaching/closing the flap. The tissue is then sutured over the exposed tooth root to keep it in place as it heals.
Free Gingival Grafts — Similar to connective tissue grafts, free gum grafts use a piece of skin taken from the roof of your mouth (without a flap being made.) Free gingival grafts are usually preferable when a large area of gum tissue needs to be restored.
Pedicle Grafts — If there is plenty of gingival tissue adjacent to the tooth with recession, it can be partially sectioned and then stretched over the tooth that’s exposed.
Allografts — Donor tissues are a safe and medically processed source (frequently used for burn victims) to prevent the need of harvesting tissue from your own body, which can sometimes be uncomfortable. As such, allografts lessen healing time.
