left upper lateral secondary incisor tooth

The left upper lateral secondary incisor is a permanent tooth that erupts around 8-9 years of age, replacing the primary lateral incisor with a single root and slightly smaller crown.

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

It functions in cutting and incising food, contributes to anterior tooth guidance during jaw movements, and is important for facial esthetics.

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

It is commonly affected by developmental anomalies including agenesis, is subject to trauma, and is a frequent focus of orthodontic and cosmetic dental treatment.
