Orthodontic treatment is often necessary for patients with endodontically treated teeth, with the objective of effective tooth movement while minimizing biological risks and discomfort. However, the impact of orthodontic forces on these teeth remains a source of clinical uncertainty, as they can trigger inflammatory responses and structural changes in both the periodontal ligament and pulp tissue. Despite well-established principles of interdisciplinary management of these cases, there is a lack of consensus on best practices particularly in relation to sequencing, timing, and managing potential complications. This review aims to address key considerations for orthodontic treatment in endodontically treated teeth, providing evidence-based guidelines to minimize risks and improve treatment outcomes.
