Common TMJ disorder symptoms include jaw pain, painful clicking or grating, difficulty opening the mouth and a jaw that catches or locks. Headaches, ear-area pain and facial muscle tenderness can also occur. These symptoms overlap with dental, ear, nerve and headache conditions, so they should not be used to diagnose yourself.
TMJ refers to the temporomandibular joint on each side of the head. Problems affecting the joints and chewing muscles are more accurately grouped as temporomandibular disorders, or TMD.
Ten symptoms worth discussing with a health professional
Pain in or around the jaw joint
Pain may sit just in front of the ear and worsen while chewing, yawning or opening widely. Note when it occurs and whether it affects one or both sides.
Painful clicking, popping or grating
Jaw sounds without pain or restricted movement are common and do not always require treatment. A new sound accompanied by pain, catching or reduced movement is more useful to report.
A jaw that locks or catches
The jaw may briefly stick or feel difficult to open or close. A jaw that is currently locked, particularly after injury, needs prompt assessment.
Limited mouth opening
You may find it harder to bite into food, brush the back teeth or open as widely as usual. Do not repeatedly force the jaw open to test it.
Pain or fatigue while chewing
Chewing muscles can feel tired, tight or sore, especially after firm foods or prolonged clenching.
Tenderness in the face or temples
The muscles in the cheeks and temples may be sensitive. Facial pain has many possible sources, including teeth and sinuses, so location alone does not confirm TMD.
Headaches associated with jaw use
Some people notice temple headaches alongside clenching or chewing-muscle tenderness. A headache should not automatically be attributed to the jaw, particularly when it is new, severe or different from your usual pattern.
Ear-area pain or fullness
The jaw joint sits close to the ear, and TMD can be felt in that area. Ear infections and other ear conditions can cause similar symptoms and may require medical assessment.
A change in how the teeth meet
Your bite may feel different during a flare or after an injury. A persistent or sudden change should be examined rather than corrected with an over-the-counter appliance.
Signs of clenching or grinding
Morning jaw fatigue, tooth wear or chipped teeth may occur with clenching or grinding, but not everyone with bruxism has TMD. A TMJ dentist can check both the teeth and jaw function.
When should you seek urgent help?
Call 000 for a serious injury, breathing difficulty, stroke-like symptoms or another life-threatening emergency. Seek prompt professional assessment for a jaw locked open or closed, significant facial swelling, fever with dental or facial pain, inability to eat or drink, new numbness or weakness, or severe pain after trauma.
A sudden severe headache, neurological symptoms, or chest pain needs medical assessment rather than being assumed to come from the jaw.
What causes TMJ disorder symptoms?
There is often no single cause. Jaw injury, arthritis, tooth clenching or grinding, and strain in the chewing muscles may contribute. Stress can increase muscle tension or clenching for some people, but that does not mean symptoms are imaginary or that stress is always the cause.
Because several conditions can mimic TMD, assessment may include your symptom history, jaw movement, muscles, joints, teeth and bite. Imaging is not automatically required for every person.
What can you do while waiting for an assessment?
Short-term measures may include choosing softer foods, avoiding gum and very wide openings, and using heat or cold if it feels helpful and is safe for you. Do not start long-term medication or use an unassessed mouthguard simply because it is sold for jaw pain.
Ask a pharmacist, dentist or doctor which pain medicine is safe for you, particularly if you are pregnant, take other medicines, have allergies, or have stomach, kidney, liver, bleeding or cardiovascular conditions.
Who may suit dental management, and who may need another clinician?
A dental assessment can be useful when symptoms occur with tooth wear, clenching, bite concerns or pain that may be coming from a tooth. Depending on the findings, care may involve education, monitoring, a professionally fitted appliance or coordination with a GP, physiotherapist or specialist.
An appliance does not suit every cause of facial pain, and irreversible changes to the teeth or bite should not be presented as a routine first answer. The correct path depends on the diagnosis.

Frequently Asked Questions
What are the most common TMJ disorder symptoms?
Common symptoms include pain around the jaw joint, painful clicking or grating, jaw stiffness, restricted opening and a jaw that catches or locks. Some people also experience facial-muscle tenderness, discomfort while chewing, headaches or pain around the ear. These symptoms can have other causes, so an examination may be needed.
Does jaw clicking always mean TMD?
No. Jaw clicking without pain, locking or restricted movement is common and may not require treatment. Assessment is more appropriate when the sound is new, painful or accompanied by catching, locking, swelling or difficulty opening the mouth. Avoid repeatedly forcing the jaw to reproduce the sound.
Can TMJ problems cause ear-area pain or headaches?
Yes, temporomandibular disorders can sometimes cause pain around the ear or temples because the jaw joint and chewing muscles are close to these areas. However, ear conditions, dental problems and headache disorders can produce similar symptoms. New, severe or persistent symptoms should not automatically be attributed to the jaw.
Who should assess a locked jaw?
A dentist, doctor or hospital emergency department may assess a locked jaw, depending on its severity and cause. Seek prompt assistance if the jaw is stuck open or closed, particularly after an injury. Call 000 if it is accompanied by breathing difficulty, significant trauma or another life-threatening symptom. Do not try to force the jaw back into position yourself.
