Step-by-step explanation:
The joint between the tooth and jaw is called the temporomandibular joint (TMJ). It allows for opening and closing of the mouth, as well as side-to-side and protraction/retraction motions of the lower jaw. The TMJ involves the articulation between the mandibular fossa and articular tubercle of the temporal bone with the condyle (head) of the mandible. It is filled with a flexible articular disc that helps to smooth the movements between the skull and mandible.
