left upper third secondary molar tooth

The left upper third secondary molar, commonly called a wisdom tooth, is a permanent tooth that erupts around 18-25 years of age (if present), with variable morphology and frequently three roots.

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

It functions to grind and crush food when present and properly positioned, though it is often absent, impacted, or misaligned due to limited space.

It is attached to the maxilla by a periodontal ligament and variable root structure when erupted, and may or may not occlude properly with the lower third molar.

It is frequently impacted or absent, often requires extraction due to pericoronitis or space constraints, and is the most evolutionarily variable tooth in human dentition.
