Swelling and pain in the tooth may be caused by apical periodontitis, and the methods to relieve the symptoms more quickly are generally open pulp cavity, incision and drainage, root canal treatment, as follows.
1. Open the pulp cavity: establish a drainage channel by opening the pulp cavity, so that the inflammatory exudate from the root apex can be discharged smoothly, reducing the pressure on the tissues in the root apex and relieving the pain.
2. Incision and drainage: When the abscess reaches submucosa or subperiosteum, timely incision and drainage can reduce inflammation and local tissue pressure and relieve pain.
3. Root canal treatment: Root canal treatment is needed to treat periapical inflammation through root canal preparation, root canal disinfection and root canal filling.
It is recommended to go to the hospital in time to receive professional treatment as soon as possible.
