If you find that your gums are abscessed and swollen with an abscess. If you want to drain the pus yourself at home, you can consider using a sterile syringe needle or a sterilized toothpick to poke the pus out of the area so that the pus will slowly flow out along the fistula. However, it is generally not recommended that patients do this at home, as it may lead to the spread of inflammation, and the pus may cause more serious disease if it is not completely exuded. Generally, if you want to treat abscessed gums, you should go to the hospital for an examination to see if the abscess is caused by an apical abscess or a periodontal abscess. Apical abscesses are treated with root canals, while periodontal abscesses are treated with the periodontal system. If an abscess has formed, a professional incision and drainage is required, after which the pus can be thoroughly drained out.
