Jaw pain and pain when opening your mouth: what could it be?
Pain near the ear, a click when you open your mouth, tiredness when chewing, or the feeling that your jaw locks usually point to the joint that connects the jaw to the skull, the TMJ. When those signs repeat, the set is often called TMD, temporomandibular disorder. The causes vary, which is why Well Clinic Odontologia investigates which one applies to you.
What is usually behind it.
Pain in the jaw joint rarely has a single cause. These are the most associated:
Grinding and clenching
Grinding or clenching your teeth, often during sleep, overloads the joint and the chewing muscles. It is one of the factors most associated with jaw pain. See the signs in teeth grinding.
How the teeth meet
When the bite does not distribute chewing force well, the joint and the muscles can work in excess, which may contribute to pain and clicking.
Stress and tension
Emotional tension often translates into clenching and into contracted facial muscles, which is associated with jaw pain and with headaches.
Everyday overload
Chewing gum for long periods, resting your face on your hand, or held postures can add load onto the joint over time.
Trauma or other causes
A blow to the face, an episode of opening the mouth very wide, or other conditions can also be involved. Only an evaluation tells one cause from another.
Seek an evaluation if you notice:
- Jaw pain or pain near the ear that persists or returns often
- Clicking or grating when you open your mouth, especially with pain alongside
- A feeling that your jaw locks or is hard to open
- Pain when chewing, facial tiredness, or frequent headaches
- Clenching or grinding, noticed by you or by whoever sleeps beside you
None of these signs is a diagnosis: they are reasons to investigate. And investigating early usually means simpler care.
The joint carries what the day leaves behind.
Jaw pain rarely lives alone. Sleep, stress, breathing, and the way the teeth meet enter the same reading, which is why the evaluation here does not stop at the joint itself.
What patients ask us.
What is TMJ and what is TMD?
TMJ is the temporomandibular joint, which connects the jaw to the skull. TMD is the name given to the set of signs when there is a disorder involving that joint and the muscles around it.
Is clicking when I open my mouth serious?
Clicking on its own is not a diagnosis. It deserves evaluation especially when it comes with pain, with a locking sensation, or when it repeats often.
Can grinding my teeth cause jaw pain?
Grinding and clenching overload the joint and the chewing muscles, and are among the factors most associated with jaw pain.
