The primary initial management of a root fracture involves reduction and immobilisation to stabilize the fractured segments and promote healing. Splinting the tooth helps maintain proper alignment, prevents displacement, and allows the periodontal ligament and pulp to recover. Immediate extraction or root canal treatment is typically avoided unless there are signs of severe displacement or pulp necrosis. Administration of antibiotics is not routinely indicated unless there is evidence of infection. Early and adequate immobilisation improves prognosis and tooth retention.
