A broken lip tie can heal itself if it is a smaller wound with less bleeding, but if it is a larger wound with more bleeding, it is difficult to heal itself. 1. Smaller incision of broken lip tie: no special treatment, after stopping bleeding completely, keep the mouth clean, avoid stimulating the wound, usually 7~10 days after the injury, the wound can be healed by itself. 2. Lip tie rupture of larger incisions: if not treated professionally, the possibility of self-healing is very low, usually under local anesthesia, the lip tie needs to be sutured to promote the normal healing of the lip tie, to restore its morphology, structure and function. If the symptoms do not improve, it is recommended to go to the hospital in time for regular treatment.
