The surgery for low labial tie is called labial tie revision or labial tie excision, which is performed on the gum tissue and is less invasive, usually leaving no scars, as follows. If the labial tie is too low, the lip will pull the gingival margin when moving, and the corresponding area is easy to accumulate plaque and other irritants, prone to periodontitis and periodontal pockets, so it is feasible to perform labial ligament revision surgery to cut off the labial ligament and change its attachment position. In severe cases, the gap between the maxillary central incisors may appear due to the thick labial ligament spacing, which affects the aesthetics. Labial ligamentectomy is required, i.e., removal of the ligament along with its fibrous attachment to the bone surface. If the above symptoms occur, it is recommended to go to the hospital in time to receive regular treatment as soon as possible.
