The tooth pain next to the tooth after extraction can be treated as follows: 1. If the alveolar bone is obviously missing in the extraction socket, resulting in the root of the tooth being exposed at the trauma and producing obvious pain when stimulated by hot, cold, sour or sweet, the granulation tissue in the socket needs to be scraped under local anesthesia and filled with bone powder to cover the root of the adjacent tooth, and the pain is relieved after complete healing; 2. If improper force is used during the extraction process, causing damage to the adjacent tooth and producing periodontal concussion. If the root of the adjacent tooth is fractured and the looseness is more than degree II, and the adjacent tooth cannot be used for chewing and eating, the adjacent tooth should be extracted and implantation should be performed immediately.
