left upper first secondary premolar tooth

The left upper first secondary premolar is a permanent tooth that erupts around 10-11 years of age, replacing the primary first molar with typically one buccal and one lingual cusp.

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

It functions to tear and grind food, providing transitional function between anterior and posterior teeth during mastication.

It is attached to the maxilla by a periodontal ligament and root (often bifurcated), and occludes with the lower first and second premolars.

It is frequently selected for orthodontic extraction for space management, important for balanced posterior occlusion, and subject to caries and periodontal disease throughout life.
