Inflammation of the tooth nerve requires a visit to the hospital for root canal treatment. Root canal therapy is currently the most effective treatment for pulpitis and is divided into three main steps: First, the pulp cavity is opened under local anesthesia and the nerve is sealed with a drug that deactivates the nerve. Secondly, the infected pulp is removed, the root canal is disinfected and prepared for root canal shaping. Third, the root canal is filled tightly with hot cement under vertical pressure. After root canal treatment, the pulp infection and inflammation are eliminated, the pain disappears, and the affected tooth can function as a normal tooth. If the inflammation of the nerve is not treated in time, the infected material in the pulp cavity will penetrate into the periapical bone tissue along the apical foramen causing periapical inflammation, resulting in pus at the root tip and abscesses in the gums. For the affected tooth to have root canal treatment, it is recommended to take oral anti-inflammatory drugs to assist in anti-inflammation, you can take cephalosporin, erythromycin and metronidazole tablets.
