If the swelling is close to the apical part of the gum, it means that the tooth is suffering from chronic periapical inflammation. In the treatment, root canal treatment should be done to the tooth to remove the infected material in the pulp cavity and remove the source of infection, and the periapical inflammation will be gradually metabolized and absorbed by the body, and the swelling of the gum will gradually disappear. If the swelling at the gums is very obvious, you can also take antibiotics in moderation, such as cephalosporin and metronidazole tablets for anti-inflammatory purposes. A packet on the gum that is close to the gum margin suggests that it may be suffering from gingival papilloma or interdental papillitis. In this case, a thorough periodontal cleaning, mainly including ultrasonic scaling and periodontal scraping, should be performed first to create a good periodontal environment, and the swollen gum area will gradually recover after a series of treatments. If the swollen gums do not absorb on their own, surgical removal is required to help restore the gums to their normal shape.
