Connective-tissue grafts
This is the most common method used to treat root exposure. During the procedure, a flap of skin is cut at the roof of your mouth (palate) and tissue from under the flap, called subepithelial connective tissue, is removed and then stitched to the gum tissue surrounding the exposed root. After the connective tissue -- the graft -- has been removed from under the palatal flap, the flap is stitched back down.
