The gums behind the large teeth, the gums behind the molars, are swollen and painful, which may be caused by wisdom tooth pericoronitis, apical periodontitis, etc. If it is wisdom tooth pericoronitis, it is feasible to rinse locally and incise and drain the pus; if it is apical periodontitis, it is feasible to incise and drain the pus and treat the root canal.
1. Wisdom tooth pericoronitis: In the acute stage of inflammation, use saline or chlorhexidine solution to rinse the inflamed area locally, and then put iodized glycerin in a blind bag, if abscess is formed, make an incision and drain the pus in time, which can relieve the local swelling.
2. Periapical inflammation: When the abscess reaches the subperiosteal or submucosal stage, make an incision and drain the pus in time. If the abscess is deeper, the incision can be enlarged and drainage strips can be placed to open up the pulpal cavity to establish a drainage channel, which can be carried out at the same time with the incision and drainage of pus, so as to carry out the perfect root canal treatment.
It is recommended to go to a regular medical institution for consultation and professional treatment with the help of a doctor.
