left lower primary canine tooth

The left lower primary canine is a deciduous tooth that erupts around 16-22 months of age, featuring a pointed cusp and single root, adapted for tearing and guiding occlusion.

It is located in the mandible on the left side, distal to the lateral incisor in the anterior region of the lower jaw.

It functions to tear and rend food, guides lateral jaw movements during mastication, and maintains vertical dimension of occlusion in the primary dentition.

It is attached to the mandible by a periodontal ligament and root, and occludes with the upper canine in a cuspid-to-cuspid relationship.

It is critical for guiding canine guidance in occlusion, maintaining primary dentition space, and its loss or pathology can affect proper occlusal guidance and eruption of the permanent canine.
