Toothache can be seen in stomatology or dentistry, it is the same thing, the department that treats teeth in hospital is called stomatology, dentistry is the name for individual outpatient clinic, the treatment items are exactly the same. If the cavity of the tooth is deep and the X-ray shows that the pulp is infected, it will be necessary to apply local anesthesia, grind the pulp cavity and place clove oil cotton ball to relieve the symptoms. 2-3 days later, the pulp will be removed, root canal preparation and root canal disinfection will be performed, and 1 week later, the root canal will be filled and the cavity will be closed. If the tooth is fractured and the gum redness and swelling are obvious, oral cephalosporin and nitroimidazole antibiotics need to be administered first and wait until the inflammation subsides before extracting the affected tooth and repairing it at a later date after the extraction socket has healed in 3 months.
