The best way to relieve pain is to go to the stomatology department in time, open the pulp and drainage, drain the blood completely, the pain will disappear. If the patient uses oral medication or cold water analgesia, the pain will only be temporarily relieved until the pain medication wears off, and the pain will gradually increase. The best treatment for acute pulpitis is root canal therapy. After the patient’s severe pain is relieved, the patient will come back for a week to have the nerve completely removed, the root canal flushed, and the tooth filled with hot cement to get complete pain relief, followed by crown restoration.
