Depending on the shape of the gum recession and the levels of bone around the teeth, areas of gum recession can be regenerated with new gum tissue using a variety of gum grafting procedures. While gum augmentation is easy to obtain, root coverage is sometimes more diffcult to obtain. These procedures are typically completed under local anesthesia with or without conscious sedation, as the patient prefers. This may involve repositioning of adjacent gum tissue to cover the recession (called a pedicle graft), or use of a free graft of gingiva, or connective tissue from the roof of the mouth. Alternatively, donor tissue, either animal or human in origin, may be used instead of tissue from the patient's own palate.
