In the case of acute pain due to periodontitis, especially periodontal abscesses, the common relief in this case is oral antibiotics, especially metronidazole, which can provide significant relief. If not, come to the hospital for consultation first to see if the pus is mature, and when it is mature, it can be incised or sometimes treated by scraping under the periodontal gums to allow the pus to drain naturally from the periodontal pockets, which can provide very significant pain relief through simple scraping treatment. After simple treatment, some antibiotics, commonly metronidazole, can be used to relieve the pain. If the gum pain is caused by inflammation of the wisdom teeth, the pain can be relieved by rinsing with hydrogen peroxide, also called hydrogen peroxide solution, plus saline, and prescribing some antibiotics and mouthwash to assist with the medication. Other rarer mucosal diseases that cause pain are less common in periodontology and are usually referred to oral mucosal medicine for treatment by an oral mucosal surgeon. There are also some relatively rare cases of necrosis and pain in the gums caused by extreme malnutrition or AIDS, which require debridement to scrape away the necrotic tissue and then a series of measures to relieve the pain, such as systemic or local antibiotics or local rinses and mouthwash-assisted medication. Sometimes in very rare cases, it is necessary to prescribe a little pain medication, such as ibuprofen, to help relieve the pain.
