Transmigration of mandibular canine teeth is a rare dental anomaly characterized by the tooth's aberrant migration through the alveolar bone. This deviation from the expected eruption pathway can lead to tooth impaction, root resorption, periodontal problems, and aesthetic concerns. The exact cause of transmigration is not fully understood, but it is believed to be influenced by a combination of genetic, developmental, and environmental factors. Early diagnosis and appropriate treatment are essential to prevent complications and achieve optimal functional and aesthetic outcomes. This case report presents a 19-year-old female with impacted left mandibular canine teeth. An interdisciplinary approach involving orthodontic therapy and surgical exposure to disimpact the transmigrated canine into the normal occlusal position. The treatment utilized modified orthodontic mechanics, including uprighting springs and temporary anchorage devices (TADs) to treat transmigration. This case also highlights the importance of early diagnosis and timely intervention for transmigrated canine teeth to prevent complications and achieve optimal aesthetic and functional outcomes.
