Tooth roots that are exposed due to gum recession may be sensitive to hot and cold foods or liquids, and they make teeth appear long. Gum recession can put you at risk of developing a cavity on the tooth root, and may lead to bone loss, eventually resulting in tooth loss. Soft tissue grafts, which move healthy gum tissue from one part of the mouth to another, can stop gum recession and bone loss and improve the esthetics of the gum line.
