What is a "premolar"?

A premolar, also known as a bicuspid, is a tooth located between the canine and molar teeth in the human mouth. Adults typically have eight premolars, four in the upper jaw and four in the lower jaw, with two on each side. Premolars have a flattened surface with one or two cusps that are suited for crushing and tearing food. They play a crucial role in the chewing process by assisting in the breakdown of food particles. Premolars also aid in maintaining proper alignment of the jaw and contribute to the overall aesthetics of the smile.
