Once the lingual ligament is broken, the patient does not experience any special pain or bleeding, so it can be ignored and treated as a lingual ligament lengthening, so the lingual ligament break is not a very serious disease. If the patient is unable to determine the extent of the lingual ligament fracture, it is recommended that the patient himself should go to the oral surgery department as soon as possible, ask the doctor for examination and treatment, and take the necessary treatment measures according to the extent of the lingual ligament fracture and the patient’s symptoms. If there is a lot of bleeding and the fracture is deep, a sterile suture operation under local anesthesia can be performed to resolve the lingual ligament fracture.
