left upper second secondary molar tooth

The left upper second secondary molar is a permanent tooth that erupts around 12-13 years of age, featuring multiple cusps and three roots adapted for grinding and crushing food.

It is located in the maxilla on the left side, distal to the first molar in the molar region of the upper jaw.

It functions to grind and crush food during mastication, providing significant masticatory force and assisting in stabilizing the posterior dental arch.

It is attached to the maxilla by a periodontal ligament and three roots, and occludes with the lower second molar.

It completes the permanent posterior occlusion, is subject to caries and periodontal disease, and its loss significantly compromises long-term masticatory efficiency and dental stability.
