Abstract
When the tooth, instead of erupting in its normal position, remains impacted and crosses midline and is seen on the opposite side of the jaw, it is termed as Transmigration; e.g., right side tooth is seen on the left side and vice-versa. This phenomenon occurs without any pathology intervening cause. Canines are commonly seen unerupted and remain impacted, but rarely seen crossing the midline and migrating to the opposite side. They are usually symptomless. Here, we present two such rare cases of transmigration of the mandibular canine, one from the right side to the left side and appearing piercing the lower border of the mandible and producing a hard bulge on the left side of the lower jaw, but without any pain. The other case is of transmigration of mandibular left canine toward the right side well below the inferior alveolar canal beyond mental foramen facing toward posterior region of the mandible and causing pain symptoms in the jaw due to its close proximity to inferior alveolar canal. It is very essential to have panoramic radiograph to detect such abnormalities at an early stage to plan treatment and avoid future complications. Cone beam computed tomography images also play an important role.
