Bumps are usually swollen gums, which may be caused by gingivitis, periodontal abscess, apical periodontitis, etc. They can be treated by general treatment, medication (e.g., metronidazole), surgery, and root canal treatment. 1. Gingivitis: Gum tissues are congested and edematous and protrude into the mouth. Patients should maintain oral hygiene and avoid spicy and stimulating food; they can use hydrogen peroxide, chlorhexidine and other drugs for local rinsing, which has anti-inflammatory effect and relieves tissue swelling; patients with poor gingival shape and fibrous gingival hyperplasia can be treated by gingivectomy and gingivoplasty. 2. Periodontal abscess: This symptom is the accompanying symptom of periodontitis in the middle and late stages of its development, and it will appear that the gum tissues are swollen and raised, forming abscesses. Antibiotics can be used to control the infection, commonly used drugs such as metronidazole, tinidazole, etc. Procaine can be used to alleviate the pain when it is severe; acute periodontal abscess can be incised and drained after the formation of abscess, chronic periodontal abscess can be periodontal flap surgery. 3. Root canal treatment: If it is caused by apical periodontitis, root canal treatment is needed to remove the source of infection in the root canal and control periapical infection in order to promote the elimination of gingival fistula. Swollen gums can be timely to the hospital, identify the cause of the relevant treatment, strictly comply with the doctor’s prescription medication.
