The scientific name for cheeks is buccae, which is Latin for "cheeks." The area between the inside of the cheek and the teeth and gums is called the vestibule or buccal pouch or buccal cavity. This region is part of the mouth and is innervated by the buccal nerve. In other animals, the cheeks may also be referred to as "jowls."
The term "buccal" is used to describe anything related to the cheek. For example, buccal mucosa refers to the inner lining of the cheeks.
