Occasionally, impacted teeth may migrate within the jawbone after root completion due to the presence of tumors or cysts. However, ectopic impaction of teeth without an identifiable cause is a rare. We report a rare case of an impacted ectopic maxillary canine located at the infraorbital margin in a 13-year-old girl. The impacted canine was located close to the orbit, nasal cavity and maxillary sinus, and considering the possibility of developing ocular symptoms in the future, extraction under general anesthesia was performed. No complications were observed postoperatively. The likely reason for impaction was growth: the canine was single-rooted, had an incomplete root and was impacted in the maxilla, which has a large amount of cancellous bone. Impacted canines may grow upward as in this case and affect the surrounding tissues. Therefore, the necessity of tooth extraction at an early stage should be explained to the patient.
