| Cause | Explanation | |-------|-------------| | Retained root tip | Apex fractured during extraction, left behind. Anterior teeth have long, fine roots – easy to miss. | | Chronic focal sclerosing osteomyelitis | Low-grade infection in bone, persists months after extraction. | | Foreign body reaction | Gelfoam, bone graft, or gauze remnant left in socket. | | Alveolar osteitis sequelae | Dry socket (days 3–5) that progressed to delayed healing and chronic inflammation. | | Iatrogenic damage | Adjacent tooth root exposure or devitalization leading to referred symptoms. | | Underlying bone pathology | Undiagnosed periapical cyst, keratocyst, or giant cell lesion – extraction doesn’t remove the lesion. | If re-downloading fails repeatedly, test your hardware
Before attempting repairs, diagnose where the corruption came from.
