Abstract Ectopic mandibular canine is a rare abnormality of tooth eruption. Ectopic mandibular canine has no obvious clinical symptoms, and is often found accidentally by radiological examinations. The current diagnostic methods for ectopic canine is mainly full-mouth tomography and cone beam computerized tomography. If ectopic canine is not detected early, and prevention and blocking measures are not taken, it will lead to impacted canine. Impacted canine can lead to severe malocclusion, increase the risk of dentigerous cyst and can also root resorption of adjacent teeth, resulting in adverse effects on the masticatory function, aesthetics, and psychology of patients. This article reports one case of blocking extraction of deciduous canine in the early stage of ectopic mandibular permanent canine and the removal gap was managed and achieved good results. Combined with the literature review, it was found that early prevention or blocking extraction of deciduous canine is the most ideal treatment method. Early intervention can improve the degree of ectopic canine, reduce the risk of impacted canine, and contribute to the stability of the oral and maxillofacial system and the health of adjacent teeth.
