PREMOLAR Meaning and
Definition
-
A premolar is a tooth situated in the mouth's dental arch, located between the canine tooth and the molar. In humans, there are two premolars in each quadrant of the mouth, making a total of eight in the whole mouth. They are positioned immediately behind the canine teeth and in front of the molars. The premolars possess a flat biting surface and have a sharp, cusped structure which helps in mastication or chewing.
Premolars have a different shape compared to canines and molars. They typically have two cusps or points, one buccal or outer cusp, and one lingual or inner cusp. The buccal cusp is usually more prominent, especially in the first premolar, while the lingual cusp may be less developed or even absent in some cases.
The primary function of premolars is to assist in the grinding and cutting of food during the process of chewing. They play a crucial role in breaking down food into smaller pieces that can be easily swallowed and digested. Furthermore, premolars also aid in maintaining proper alignment and occlusion of the dentition.
Premolars are permanent teeth that erupt once the deciduous or baby teeth have been shed. They have a root structure firmly anchored to the jawbone by periodontal ligaments, which provide stability and support to the tooth. Proper oral hygiene and regular dental check-ups are necessary to ensure the health and longevity of premolars, as they are an integral part of the dental structure and overall oral well-being.
