Tooth pain with swelling occurring in the lining of the mouth may be caused by infection of the temporomandibular space due to the spread of apical periodontitis in the tooth. The treatments are incision and drainage and root canal treatment as follows.
1. Incision and drainage: the incision and drainage route of temporomandibular gap infection can be chosen from intraoral or extraoral, intraoral incision is made at the turning point of the mucous membrane of the lateral vestibule of the maxillary tubercle, and it is separated to the pus cavity, while extraoral incision is made under the angle of the lower jaw to make a curved incision to enter the pus cavity.
2. Root canal treatment: Teeth with apical periodontitis need to undergo root canal treatment, which includes root canal preparation, root canal disinfection and root canal filling to promote the healing of periapical lesions.
It is recommended to go to the hospital in time to receive professional treatment as soon as possible.
