Mandible, commonly known as jawbone, is an essential part of the skull which is responsible for holding the lower teeth and providing support to the face structure. Other synonyms to describe this bone include the lower jaw, lower mandible, and maxillae. The structure is crucial to chewing, speaking, and breathing. Other synonyms to describe the mandible or jawbone include alveolar arch, dental arch, gnathic bone, and submaxilla. The jawbone and its joints are also referred to as the temporomandibular joint which is responsible for the movement of the jaw when one eats, talks or breathes. The health and proper functioning of the jawbone are critical to the overall well-being of an individual.
