Abstract: The incidence of permanent canines failing to erupt in the mandible is not as common, and, therefore, not as well reported, as that in the maxilla. Mandibular canines have important functional and aesthetic purposes and knowledge of this uncommon condition is essential for those involved with the management of these cases. This article explores the aetiology, assessment and treatment options available to manage this condition, using examples from treated cases within our department.

Clinical relevance: An understanding of the aetiology, assessment and various treatment options available to manage impacted and transmigrated mandibular canines will inform better treatment planning.
