What TMJ and TMD mean
The TMJ is a hinge and sliding joint with a small cartilage disc between the jawbone and the skull. Powerful muscles open, close and move the jaw from side to side. TMD is an umbrella term for pain and dysfunction of these joints and muscles. Most TMD is muscular, related to overuse and tension; some involves the disc, which can slip and click; and a smaller group involves arthritis of the joint.
Common TMJ symptoms
- Aching pain in the jaw, in front of the ear, in the cheek or in the temple.
- Pain when chewing, talking for a long time, yawning or opening the mouth wide.
- Clicking, popping or grating sounds when opening or closing; see jaw clicking when chewing.
- Limited mouth opening, or the jaw catching or locking.
- Stiffness or tiredness of the jaw, especially in the morning.
- A change in how the teeth fit together, or tooth sensitivity without a dental cause.
- Headaches, often at the temples, and neck or shoulder tension.
TMJ and ear symptoms
Because the joint sits right in front of the ear canal and shares nerve pathways with the ear, TMD frequently causes earache, a feeling of fullness or pressure, ringing (tinnitus) or a sense of imbalance, while the ear itself looks normal. Clues that the jaw is the source include pain when chewing, tenderness in front of the ear or in the cheek muscles, clicking, and symptoms that are worse after clenching or a long day. An ENT examination of the ear and throat is still important to rule out ear infections and other causes of referred ear pain.

Causes and risk factors
- Clenching and grinding (bruxism): during sleep or when concentrating or stressed.
- Stress and anxiety: increase muscle tension and pain sensitivity.
- Overuse: chewing gum, biting nails, chewing tough foods or long periods of talking.
- Disc displacement: the disc moves out of position, causing clicking and sometimes catching.
- Injury: a blow to the jaw, dental treatment with the mouth open for a long time, or whiplash.
- Arthritis: osteoarthritis or inflammatory arthritis of the joint.
- Posture and neck problems: a forward head posture can add strain; see forward head posture.
- Other pain conditions: TMD is more common in people with chronic headaches, neck pain or widespread pain.
Self-care that helps most people
- Eat softer foods and cut food into small pieces for a couple of weeks; avoid chewing gum and very chewy foods.
- Avoid opening the mouth very wide; support the chin when yawning.
- Practise the jaw rest position: lips together, teeth apart, tongue resting on the roof of the mouth.
- Notice and stop daytime clenching; set reminders to check your jaw.
- Apply warmth to the jaw muscles for 10 to 15 minutes, or a cold pack if it feels better.
- Massage the cheek and temple muscles gently in small circles.
- Manage stress with relaxation, regular exercise and good sleep.
- Use simple painkillers for short periods if suitable.
Gentle jaw exercises
- Controlled opening: with the tongue on the roof of the mouth, open slowly as far as comfortable without clicking, then close; 10 times.
- Relaxed opening in front of a mirror: open and close in a straight line without the jaw deviating to one side; 10 times.
- Side-to-side glides: with teeth slightly apart, move the jaw gently to each side; 10 times.
- Chin tucks: to reduce neck strain; 10 repetitions.
Exercises should not cause pain. A physiotherapist experienced in jaw problems can tailor them to you.
Professional treatment options
- Physiotherapy: manual therapy, jaw and neck exercises, and posture and habit training.
- Dental splint or night guard: made by a dentist, can reduce the effects of night-time grinding and ease symptoms for some people.
- Medicines: short courses of anti-inflammatories; some people with chronic pain benefit from other medicines prescribed by a doctor.
- Psychological approaches: cognitive behavioural therapy and stress management for long-lasting pain.
- Injections: into the joint or muscles in selected cases.
- Surgery: rarely needed, for specific joint problems that do not respond to other treatment.
Most people improve with conservative treatment, and irreversible procedures such as grinding down teeth are generally not recommended as a first step.
When to see a doctor urgently
- The jaw is locked open or closed.
- Jaw pain with chest pain, breathlessness or sweating, which can be a heart attack; call emergency services.
- Swelling of the face or jaw with fever.
- Numbness of the face or chin.
- Pain after a significant injury to the jaw.
- Unexplained weight loss, a persistent lump, or a change in the bite that keeps progressing.
Key points to remember
- TMD causes jaw pain, clicking, limited opening, headaches and ear symptoms.
- Earache with a normal ear examination is often caused by the jaw.
- Self-care, gentle exercises and physiotherapy help most people.
- A locked jaw, facial swelling with fever, or jaw pain with chest pain need urgent care.
Questions about TMJ symptoms
These answers are general information and do not replace an examination or individual medical advice.
What are the first signs of TMJ problems?
Often jaw tiredness or ache when chewing, clicking, morning stiffness, or pain in front of the ear.
Can TMJ cause ear pain and ear fullness?
Yes. The joint is right in front of the ear and commonly causes earache, fullness or ringing with a normal ear.
Can TMJ cause headaches?
Yes, especially at the temples, because the chewing muscles attach there.
Does TMJ go away on its own?
Many cases improve within weeks to months with self-care. Persistent symptoms benefit from professional treatment.
Is jaw clicking without pain a problem?
Painless clicking is common and usually does not need treatment unless the jaw catches or locks.
Who treats TMJ disorders?
Dentists, physiotherapists, ENT specialists and maxillofacial surgeons, often working together depending on the cause.
