The main component of the cheecks is the buccinator muscle.
The muscle that resides in the cheek is names the buccinator and is innervated by the facial nerve. It is primarily a muscle of facial expression. Its function in mastication (chewing) is to push the food, with the aid of the tongue, to the opposite side of the mouth. It is, however, only able to form part of the inward movement of the cheeks; the rest is caused by negative pressure (semi-vacuum) being created by the action of the inferior tongue muscles pulling the tongue down and back.
The buccinator muscle is an important muscle in the cheek that plays a role in helping to keep food in contact with the teeth during chewing. In orthodontics, understanding the function of the buccinator muscle is important for managing aspects of orthodontic treatment that may be affected by muscle activity, such as the positioning of braces or functional appliances. Orthodontists may consider the influence of the buccinator muscle on oral function and treatment outcomes when planning a patient's treatment.
