A swollen bag in the gums of a broken tooth may be chronic apical periodontitis, periodontal abscess, combined periodontal-pulp lesion, which requires root canal treatment, periodontal sequence treatment or extraction.
1. Chronic apical periodontitis: the tooth usually has obvious carious cavities and bacterial invasion, spreading to the pulp and periapical tissues, thus forming a draining abscess-like fistula at the gums. Root canal treatment is needed to remove the inflamed pulp.
2. Periodontal abscess: mainly due to resorption of alveolar bone, resulting in the collection of bacteria in the periodontal pockets, the inflammation is manifested as swelling of the gums. Periodontal sequence treatment (basic periodontal treatment, periodontal medication, periodontal surgery and periodontal maintenance treatment) is needed to remove as much bacteria as possible around the teeth and preserve the affected teeth.
3. Combined periodontal-endodontic lesions: The pulp and periodontal tissues of the affected tooth are infected at the same time, resulting in abscesses in the gums. This type of tooth requires both root canal treatment and periodontal sequential treatment, and if the prognosis is not good, it can be extracted directly.
It is recommended that patients with abscessed gums go to a regular hospital stomatology department for a definitive diagnosis and treatment.
