Torn ligaments in the oral cavity usually recover in 5-7 days if there are no other special circumstances. The ligaments in the oral cavity are mainly divided into the labial, buccal and lingual ligaments. The labial and buccal ligaments are located between the alveolar ridge and the labial and buccal mucous membranes, and the lingual ligament is located in the midline of the mandibular floor of the mouth. Oral ligaments are often torn due to trauma, etc. If the ligament is not severely torn and there is no obvious, large amount of bleeding, it usually does not require special treatment, and most of it will heal slowly in 5-7 days. If the patient is unable to determine the extent of the tethered ligament tear, consider going to the oral surgery for examination, diagnosis and treatment, if the bleeding is much, the fracture is deep, consider local anesthesia under the debridement suture, usually 5-7 days after the operation to remove the stitches can be recovered. It is recommended that during the healing period of intraoral ligament tear, keep good oral hygiene, can be combined with the use of mouthwash to prevent infection; light diet, avoid spicy and stimulating food; do not always pull it, so as not to cause delayed healing of the wound.
