For swollen teeth, you can choose to take oral roxithromycin plus metronidazole tablets, or you can choose to use amoxicillin or cephalosporins, or if you are allergic to penicillin, you can use erythromycin. In addition, if the gum swelling is serious and there is localized pus, you can do localized rinsing, such as using hydrogen peroxide and saline alternately, and you can apply iodine glycerin locally, which can promote the gum swelling and pain to subside quickly. At the same time, if the gums are swollen and there is a low-density image at the apical part of the root on radiography, this kind of root canal treatment is usually chosen to promote the swelling of the gums to subside. If the jaw swelling is more serious, this case can choose the intravenous infusion method to promote the reduction of tooth swelling. Common anti-inflammatory drugs can be used such as cephalosporin or erythromycin, and it is recommended to use mouthwash, such as using boric acid solution or estradiol solution.
