Transmigration is defined as the migration of an impacted tooth across the midline by more than half of its length. The etiology and exact mechanism of transmigration is still not clear, although a number of factors have been suggested. Possible etiological factors are premature loss of deciduous teeth, retention of the deciduous canine, crowding, spacing, supernumerary teeth, and excessive length of the crown of the mandibular canines. This case report presents a case of an horizontally impacted permanent lower right mandibular canine and its management. Early diagnosis and appropriate intervention prevents the possible future complications caused by the transmigrated teeth. Therefore, clinical evaluation followed by a detailed radiographic screening is very important for optimal management of the tooth.
