Gum swelling and pain caused by fire can be promoted by taking metronidazole tablets or tinidazole tablets orally, together with cephalosporin, amoxicillin, roxithromycin, azithromycin or erythromycin. If the local gum swelling is heavy and fluctuating, a local incision can be made to promote its drainage, which can quickly reduce the swelling and relieve the pain. If the pain is severe, you can also choose to use pain medications such as fenbendazole or acetaminophen, or you can choose loxoprofen sodium tablets, etc. If necessary, if the gum swelling is found to be due to inflammation of the root tip of the tooth, you can choose to have dental treatment. If the swollen gums are caused by periodontal disease, it is recommended to maintain oral hygiene and, if necessary, to scaling. It is also recommended to have regular check-ups and not to eat spicy and irritating foods, which will help the swollen gums to subside.
