What Exactly is the Temporomandibular Joint (TMJ)?

The temporomandibular joint (TMJ) is a complex structure that acts like a sliding hinge, connecting your jawbone (mandible) to your skull (temporal bone). You have one TMJ on each side of your jaw. Because of the importance of this joint you use it when you talk, chew, or yawn.

This small joint is responsible for a wide range of movements, including:

Opening and closing your mouth
Moving your jaw forward (protrusion) and backward (retraction)
Moving your jaw from side to side

When the TMJ functions smoothly, these movements are effortless and pain-free. However, when the joint is misaligned, injured, or inflamed, it can lead to a variety of issues collectively known as temporomandibular joint disorders (TMD). A proper perspective on common TMD issues can provide proper function.

Taking Control of Your TMJ Health

Understanding the anatomy and function of the TMJ is the first step toward addressing jaw pain and maintaining overall wellness. By dispelling common myths and promoting a balanced view of TMJ health, this guide empowers you to make informed decisions about your care. Whether you seek professional treatment or focus on preventative strategies, prioritizing your TMJ health can significantly improve your quality of life.
