When swollen gums lead to facial pain, the following treatments are performed: 1. Ultrasonic scaling is needed to remove large pieces of calculus present on the tooth surface, to reduce the stimulation of the gums, and to manually scrape away the subgingival calculus, diseased bone and granulation tissue attached to the root surface. 2. 3% hydrogen peroxide solution and saline are used to rinse the residual material in the periodontal pockets and to decompose anaerobic bacteria and inhibit bacterial infection. 3. Swollen gums lead to suppuration and When fluctuating sensation is produced, incision can be made under local anesthesia to separate the abscess cavity and place drainage strips. 4. Hot compresses or physical therapy can be applied to the swollen area of the face to promote the absorption of exudate, and systemic application of cephalosporin and nitroimidazole antibiotics to speed up anti-inflammation.
