Swollen gums and swollen face will go down in about 7-10 days, but they need to be treated with local oral therapy and anti-inflammatory treatment. The most serious factor for swollen gums and swollen face is having pericoronitis of wisdom teeth, which causes a series of phenomena such as pain, facial swelling, restricted mouth opening, and swollen jaw lymph nodes. The inflammation can be brought under control with adequate antibiotics, and the inflammation will gradually disappear and the symptoms will be relieved after 7-10 days of anti-inflammatory treatment. In addition, periapical inflammation and periapical abscess can also lead to pus in the gums corresponding to the apical area and even facial swelling, which requires oral erythromycin and cephalexin with metronidazole to reduce inflammation. At the same time, root canal treatment should be performed on the corresponding affected tooth to unblock the pulp chamber and root canal and drain the pus, remove the infected material from the root canal and seal in anti-inflammatory medication. After a series of treatments, the facial swelling will be eliminated in about a week.
