Usually, when a maxillofacial interstitial infection occurs, it needs to be treated with an infusion of fluids, with an IV drug of etidimicin sulfate plus levonidazole, with a saline flush tube in between, which takes 3 days. Abscesses are somewhat limited, and once interstitial infections occur, they all recover only after 3 days of swelling. Therefore, there are the following notes in this process: First, the diet should be light and avoid spicy and irritating food. Second, cold compresses should be applied when there is swelling, and cold compresses should be applied for 24 hours to prevent the spread of abscess. Third, after 48 hours, the abscess has been confined and no longer grows, then hot compresses are needed to make the already swollen abscess subside. In addition, after the abscess returns to normal, it is necessary to go to the stomatology department to treat the affected tooth in time, which is very necessary because there are many patients who do not treat the abscess in time, and then the next abscess will occur.
