A swollen pile of flesh from an inflamed wisdom tooth that has been hurting for 4 days may have triggered pericoronitis. Since wisdom teeth are the last teeth to erupt in the mouth, they often cannot erupt normally because the space is too small, so they may be covered by a gingival flap around the crown, and a deep blind pocket will be formed between the gingival flap and the crown. If you eat and drink improperly or do not clean in a timely manner, food residue will remain in the blind pocket, which will generate mixed bacteria and lead to pericoronitis of the wisdom tooth. In addition to severe pain and swelling of the local tissues at the gingival area of the wisdom tooth, the patient may also experience overflowing pus in the gingival and periodontal pockets, as well as painful swallowing, difficulty in opening the mouth, difficulty in speaking, and even fever, headache, loss of appetite, and general malaise. It will affect the physical health and psychological state to a greater extent, so it is recommended to go to the hospital immediately to diagnose and receive treatment: 1, general treatment: warm water or saline rinse can be used to improve local blood circulation, relieve muscle spasm, and promote the dissipation of inflammation, so that patients feel comfortable; 2, drug treatment: after medical diagnosis, with the help of doctors to remove food debris, necrotic tissue in the gingival pockets, and then use hydrogen peroxide solution, potassium permanganate solution, chlorhexidine solution, etc. repeatedly rinse the blind pocket until the pus becomes clear, and then local topical or oral antibiotics, such as penicillin, clindamycin, metronidazole, tinidazole, etc. can be used for anti-inflammatory and pain-relieving treatment; 3, surgical treatment: the abscess formed is incised and drained, and after the inflammation subsides, for patients with enough space for the wisdom tooth to emerge, pericoronal gingival flap removal can be taken to help exposure of the crown. For the wisdom teeth that are not in the right position and do not have enough eruption position, it is recommended to take extraction after thorough anti-inflammation; 4, daily care: wisdom teeth pericoronitis patients in daily life should maintain oral hygiene, daily warm water or salt water rinse, morning and evening brush teeth, teeth with food residue timely cleaning.
