Periodontal surgery is a procedure that re-contours and reshapes the bone and gums that hold the teeth in place. Periodontal surgery is performed on the bone and overlying gum tissues that have been damaged by periodontal disease. The objective of periodontal surgery is to reduce periodontal pockets. During the procedure, infected bone and gum tissue are removed and areas where bacteria can hide are cleaned and smoothed out. This will allow the gums to better reattach to healthy bone and eliminate periodontal pockets. Achieving the goals of periodontal surgery usually exposes more tooth structure or causes elongated teeth appearance. In some cases the diseased bone or tissue may need to be regenerated through bone or gum grafts. This procedure is performed under local anesthetic.
