What causes swelling at the tooth root?

Possible causes of root swelling may include the following: 1. Trauma: Injury to the tooth from impact or biting hard objects can lead to root fracture, which may cause swelling and pain in the tooth root. 2. Periodontitis: Long-term bacterial irritation from dental plaque can affect periodontal tissues, potentially causing redness, swelling, and pain of the gums, pus discharge from periodontal pockets, and tooth mobility. 3. Pulpitis: Following exposure or injury to hard dental tissues near the pulp, bacterial invasion may lead to spontaneous pain, stimulated pain, radiating pain, and may be accompanied by root swelling. 4. Periapical Periodontitis: Infection of the dental pulp caused by dental caries or pulp diseases may spread to the periapical tissues, resulting in swelling of the tooth root. 5. Other disease-related factors: Conditions such as periodontal abscess, root tumors, pericoronitis of wisdom teeth, and acute periapical inflammation may also cause root swelling. The above conditions may lead to root swelling. Appropriate treatment measures should be determined based on specific symptoms and diagnostic findings.
