Have you ever experienced waking up in the morning and wanting to yawn, only to find your jaw stiff and painful, or while eating an apple, you open your mouth a bit wider and suddenly hear a crackling

In our lives, many people first hear the term(TMJ)when they are troubled by lower jaw pain or stiffness. Under normal circumstances, these joints are very strong, butonce inflammation occurs, it can lead to intractable, severe pain and functional impairment.

What you may not know is thatlong-term looking down at mobile phones, resting your chin on your hand while thinking, long-term side sleeping/stomach sleeping, etc.can all be triggers, and studies have shown that about72%of TMD patients also havecervical spine dysfunction.

The temporomandibular joint is located at the junction of the jawbone and the temporal bone, one on each side, just in front of the ears. This joint is not only composed of bones but also connected by muscles responsible for chewing and opening the mouth, and there is a small disc(called the “articular disc”)between the bones, which acts like the discs between the vertebrae,providing cushioning for the joint. Uniquely, the TMJ disc is the only joint disc in our body that can regenerate, thanks to its good blood supply.

Although the TMJ has a strong ability to recover, like other joints in the body, it can also be troubled by inflammation and functional disorders.Temporomandibular joint dysfunction(TMD)refers topain in the jaw joint and surrounding muscles, which can significantly limit or cause pain during functions such as eating, opening the mouth, and yawning.Symptoms of TMD include:●Clicking or popping sounds from the joint;●Intermittent locking of the mouth;●Headaches(usually on the temples on both sides of the head);●Neck pain or stiffness.

Many patients find that the pain and stiffness are most pronouncedupon waking in the morning or during eating.

It is worth noting that the temporomandibular joint and the cervical spine, especially theupper cervical segment(C1-C3), have a close anatomical and functional connection. Dysfunction of the occipitoatlantal joint(the connection between the head and the first cervical vertebra)often interacts with TMD. This is because the nerves and muscles that control jaw movement have a complex interaction with the structures of the neck. Studies have shown thatabout 72% of TMD patients also have cervical spine dysfunction, especially problems in the upper cervical segment.* The symptoms of temporomandibular joint disorders may also be related to psychological, genetic, traumatic, cervicogenic factors, and central sensitization, among other causes.
