left lower secondary canine tooth

The left lower secondary canine is a permanent tooth that erupts around 9-10 years of age, replacing the primary canine with a pointed cusp and single root adapted for tearing.

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 the jaw during lateral excursions, and is the longest-rooted anterior tooth providing stability.

It is attached to the mandible by a periodontal ligament and long single root, and occludes with the upper canine in canine guidance.

It is critical for establishing proper occlusal guidance, is often a focus of orthodontic treatment, and its position and health impact overall anterior dental esthetics and function.
