What Is a Jaw Joint?
A jaw joint is the connection between the lower jaw and the skull that lets the mouth open, close, move forward, and shift side to side. Each side of the face has one jaw joint. The joint includes bone surfaces, a cushioning disc, ligaments, and muscles that guide movement.

Key Takeaways About Jaw Joint
- Two joints connect the lower jaw to the skull.
- A cushioning disc helps guide smooth jaw movement.
- Jaw joint and TMJ disorder describe different concepts.
How Jaw Joint Works
A jaw joint works as a paired hinge and sliding connection. Each joint sits in front of the ear, where the lower jaw meets the skull. A small disc separates the joint surfaces and helps distribute pressure as the mouth opens, closes, or shifts. Ligaments and muscles guide the motion and help limit excessive movement.

Clinicians consider jaw opening, side-to-side motion, muscle tenderness, and movement quality when assessing the area. Smooth motion usually involves coordinated action from both joints. A change on one side can affect the path of the lower jaw and may alter how the teeth meet. Temporomandibular joint is the anatomical name, while TMJ disorder describes a group of problems involving the joint or nearby muscles.
From the Arrowhead Clinic Chiropractic - Albany team
When we assess the jaw joint, we observe opening and closing, compare movement on both sides, and check nearby muscles for tenderness or tension. We also consider neck posture and movement because the jaw and neck can influence each other during daily activities. Our findings help guide TMJ Treatment discussions.
Jaw Joint in Practice: A Real-World Example
A person may notice jaw stiffness while chewing breakfast and feel the lower jaw shift slightly during opening. During TMJ Treatment, we may examine the movement pattern and nearby muscle tension to understand which areas need attention.
