Canines

Canines sit at the corners of the arch and guide the jaw in side-to-side movement. The maxillary canine has the longest root in the mouth, about 17 mm, which raises the canine eminence over it. On both canines the mesial cusp ridge is shorter than the distal, and the mandibular canine is the anterior tooth most likely to have a split root.
