Ectopic eruption of permanent canines

By | August 18, 2023

A 24-year female presented to the outpatient department of operative dentistry with a chief complaint of pain and mobile left mandibular canine. Clinical examination revealed mobile retained deciduous canine and Ectopic eruption of both permanent mandibular canines.


This particular dental phenomenon involves the anomalous positioning and eruption of permanent canine teeth within the oral cavity. It is crucial to underscore the significance of this occurrence, as it can lead to disruptions in the normal dental alignment and occlusion. Ectopic eruption of permanent canines may present challenges in terms of both aesthetics and functional dentition.

The etiology of this condition can be attributed to a combination of genetic predisposition, local anatomical factors, and developmental anomalies within the dental arch. The specific mechanisms underlying the ectopic eruption of permanent canines require further in-depth investigation, given the multifaceted nature of the oral environment and its intricate developmental processes.

Efforts to manage and address ectopic eruption of permanent canines necessitate a comprehensive approach. Early detection through regular dental examinations is pivotal, enabling timely intervention to guide the eruption trajectory and prevent potential complications. Orthodontic interventions, involving the use of braces, aligners, or other corrective appliances, are commonly employed to guide the mispositioned permanent canines into their proper alignment within the dental arch.

While the management of ectopic eruption of permanent canines encompasses a range of strategies, it’s essential to acknowledge that individual cases may exhibit variations in severity and clinical presentation. Therefore, a tailored approach to diagnosis and treatment is imperative, taking into account the specific circumstances of each patient. As a consequence, research and clinical endeavors in this domain remain essential to advancing our understanding and refining our management strategies for this dental anomaly.
