Swollen and painful gums next to wisdom teeth are usually due to the process of eruption of wisdom teeth, which produces blind pockets in the gums and is prone to food impaction and gum suppuration. Gum redness and swelling are particularly prone to jaw and facial interstitial infections, which require local rinsing. You can go to the stomatology department and use hydrogen peroxide and saline alternately to rinse out all the pus and food residue in the blind pockets of the gums, and after drying them, put iodine glycerin or minocycline hydrochloride in the blind pockets to promote the recovery of healthy gums, and use mouthwash such as rehabilitative new liquid. It is also recommended to take oral anti-inflammatory drugs such as cephalosporin and amoxicillin with metronidazole tablets. If you have allergies, you can use roxithromycin. If the pain is heavy, you can choose to use pain-relieving drugs such as ibuprofen and fenpropathrin.
