left lower lateral secondary incisor tooth

The left lower lateral secondary incisor is a permanent tooth that erupts around 7-8 years of age, replacing the primary lateral incisor with a single root and slightly smaller crown.

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

It functions in cutting and incising food, contributes to anterior tooth guidance during jaw movement, and assists in facial esthetics.

It is attached to the mandible by a periodontal ligament and single root, and occludes with the upper lateral and central incisors.

It is important for establishing proper permanent occlusion, anterior esthetics, and is commonly affected by developmental anomalies, trauma, and orthodontic treatment throughout life.
