The onset of peri-coronary wisdom teeth, due to mild symptoms, is often ignored by patients and delayed, resulting in the rapid development of inflammation, the condition of peri-coronary wisdom teeth aggravated. The onset of wisdom tooth pericoronitis is painful and can cause severe facial swelling. How to treat and prevent wisdom tooth pericoronitis? The wisdom tooth pericoronitis treatment one: systemic treatment wisdom tooth pericoronitis acute period should be based on the degree of inflammation and systemic response, choose the appropriate amount of antibiotics, and pay attention to systemic support treatment, such as mild symptoms can be oral methotrexate 0.2g, 3 times a day, cotrimoxazole 1.0g, 2 times a day, etc.. For severe symptoms, 8 million units of penicillin can be administered intravenously once a day, and 250ml of methotrexate injection once a day. For early wisdom tooth pericoronitis can be stopped by local physiotherapy to stop the pain, gingival pockets near the formation of abscesses, should be promptly incised and drained. Local treatment is also important. Patients should pay attention to keep the mouth clean, and can use warm disinfectant rinse, such as oral tide, chlorhexidine mouthwash, etc. At the same time, 1% to 3% hydrogen peroxide solution and saline can be used to repeatedly rinse the gingival pockets alternately to remove the pus, bacteria, food residue, etc. from the gingival pockets until the overflow is clear. Wisdom tooth pericoronitis treatment method No. 3: pathogenic treatment When the inflammation turns into chronic phase, it is proved by X-ray that the wisdom tooth is impossible to erupt, or when the corresponding contralateral teeth are not in proper position or have been extracted, the wisdom tooth should be extracted as soon as possible to prevent the recurrence of wisdom tooth pericoronitis. For wisdom teeth that are in normal position, have sufficient eruption sites, and have normal opposing teeth, pericoronal gingival flap removal is feasible to eliminate gingival pockets. If pericoronitis is not treated in a timely manner, it can become chronic and later recur, even leaving a fistula. If the inflammation continues to spread, the following complications can occur. For example, it may spread to the subperiosteum to form a subperiosteal abscess; or pus may flow forward along the lateral bone of the mandible to form an abscess or gingival fistula on the buccal side of the equivalent of the first or second mandibular molar; or it may expand outward to form a subcutaneous abscess in the buccal area or penetrate the skin to form a skin fistula. It is necessary to have regular scaling and oral examination, and when wisdom teeth are found to be malformed, they should be extracted immediately to avoid the potential threat of wisdom teeth.
