If the gums are red, swollen, hot, painful and have pus pockets, it is possible to puncture them. When the abscess is punctured, a small amount of pus can be released, and the pus can be released to reduce the size of the abscess, which not only helps the inflammation to recover, but also relieves the pain. However, puncturing the abscess requires the use of a sterilized syringe needle. Usually, if purulent exudate is found after puncture, further abscess incision and drainage disposal is needed and drainage strips are left in place so that the incision does not heal on the second or third day, resulting in poor secretion of purulent fluid, and the drainage strips are withdrawn after the purulent secretion is completely cleared. At the same time, after the inflammation has healed, dental film imaging should be performed to determine the location and condition of the diseased tooth and to provide symptomatic treatment to avoid the recurrence of the abscess.
