The joint in front of your ear is the temporomandibular joint, and problems affecting it and the muscles around it are grouped under the label TMD, or TMJ as most people say. It is common, it is usually muscular rather than structural, and most episodes settle over weeks to months with conservative care.
That is the reassuring part. The practical part is knowing which symptoms point to muscle strain that will pass, which point to the joint itself, and which need somebody to look at you sooner rather than later.
Most jaw pain is muscle, and muscle recovers
The muscles that close your jaw are powerful and they work all day. Clenching during stress, grinding at night, chewing gum for hours, long dental appointments, and holding tension in the face all overload them. The result is a dull ache at the side of the face or the temple, tenderness when you press the muscle, tiredness while eating and sometimes headaches.
Muscular pain tends to be worse at certain times of day, spread over an area rather than pinpointed, and eased by rest and heat. It also tends to come in episodes that resolve. This is the version most people have, and it is the version most likely to improve with simple measures.
Clicking without pain is common and usually not a problem
Inside the joint sits a small disc that should glide with the jaw. If it slips slightly out of position and snaps back as you open, you get a click. A great many people have a clicking jaw for years with no pain and no loss of function, and it needs no treatment.
What matters more than the noise is whether anything else changed. Clicking that starts hurting, clicking that stops suddenly and is followed by limited opening, or a jaw that catches, locks open, or will not open more than a couple of finger widths are all reasons to get assessed rather than to wait and see.
- Painless clicking on its own generally needs no treatment
- A jaw that locks open or closed needs seeing urgently
- Opening narrowing over days or weeks needs assessment
- New pain in a joint that used to just click is worth reporting
What a dentist can genuinely help with
A dentist is the right first stop because much of what causes jaw pain is dental in origin or masquerades as it. They can check whether a cracked tooth, a failing filling, an infection or a wisdom tooth is the actual source, because pain from a lower back tooth is felt in the jaw and ear very convincingly.
They can examine the joint and muscles, measure how far you open, look for the wear patterns that go with grinding, and make a night guard where clenching is a driver. They can also adjust a filling or crown that is sitting high, coach jaw rest and exercises, and refer on when the picture suggests something beyond ordinary muscle strain.
What a dentist cannot fix, and what to be careful of
A dentist cannot cure arthritis in the joint, reposition a badly displaced disc, or resolve pain that is coming from a nerve, the neck or a widespread pain condition. Those need a physician, an oral and maxillofacial specialist, a physical therapist, or a combination.
Be cautious about anyone proposing to permanently change your bite as a first line treatment for jaw pain, whether by grinding down teeth, crowning many teeth or starting orthodontics. Those are irreversible, expensive, and not the accepted starting point. Reversible measures come first, and they resolve most cases without touching a tooth.
The self care that actually has support behind it
Conservative care is the mainstay, and it works for most people. Rest the joint by eating softer food for a couple of weeks, cutting food small, and avoiding gum, chewy bread, ice, hard candy and wide yawning. Moist heat for 15 to 20 minutes a couple of times a day relaxes the muscle, and some people prefer cold on an acutely painful joint.
Add awareness through the day: lips together, teeth apart, tongue resting on the palate is the correct rest position, and most people who clench are not aware they are doing it. Ordinary painkillers you would take for a headache can cover a bad patch. Gentle jaw exercises help many people, and getting them from a dentist or physical therapist beats copying them from a video, since the right exercises depend on whether the problem is muscular or in the joint.
- Soft food and small bites for two weeks
- Moist heat, 15 to 20 minutes, once or twice a day
- Lips together, teeth apart, through the day
- No gum, ice chewing or wide yawning while it settles
When to stop managing it and get seen
Book an appointment if pain lasts more than two or three weeks despite rest, if it is stopping you eating or sleeping, if opening is getting narrower, or if the jaw locks. Get urgent care rather than a routine appointment for swelling over the joint or in the face, fever alongside the pain, jaw pain after a blow or fall, or a sudden inability to close your teeth together properly.
One more thing worth knowing: pain in the jaw can be referred from the heart, particularly in women, so jaw pain that comes with chest discomfort, breathlessness, sweating or nausea is an emergency call, not a dental appointment.

The short version
- Most jaw pain is muscular, comes in episodes, and settles with rest, heat and habit changes.
- Painless clicking usually needs no treatment, but locking or narrowing opening does.
- A dentist should first rule out a tooth, since lower back teeth refer pain to the jaw and ear.
- Reversible treatment comes first, and permanently reshaping the bite is not a starting point.
- Jaw pain with chest discomfort, breathlessness or sweating is an emergency call, not a dental one.

Frequently asked
Will a night guard cure my TMJ pain?
It helps many people, especially where clenching or grinding is driving the pain, but it is not a cure and it does not work for everyone. A guard changes the load on teeth and muscles rather than repairing the joint. It works best alongside jaw rest, heat, and attention to stress and sleep. Give it several weeks.
Should I see a dentist or a doctor for jaw pain?
Start with a dentist, because toothache from a cracked or infected back tooth mimics jaw pain closely and is the easiest thing to rule out. If the teeth are healthy and conservative care is not helping after a few weeks, the next steps are a physician, a physical therapist or an oral and maxillofacial specialist, often together.
Does TMJ go away on its own?
Frequently, yes. Many episodes settle within weeks to a few months with rest, softer food, heat and reduced clenching, and symptoms often fluctuate rather than steadily worsen. What should not be left alone is a jaw that locks, opening that keeps narrowing, or pain that is stopping you eating or sleeping normally.
