The temporomandibular joint (TMJ) connects the lower jaw to the skull, just in front of each ear. Speaking, chewing, swallowing and yawning all depend on this joint working together with the chewing muscles. Inside the joint, a small disc acts as a cushion between the bony surfaces.

Temporomandibular disorders (TMD) is an umbrella term for a group of conditions affecting the joint, the disc and the surrounding muscles. It is not a single disease. In some people the problem is mainly muscular (myofascial pain); in others the disc has changed position; and in some there is wear or inflammation of the joint surfaces. So ‘jaw joint pain’ can describe quite different situations, and good treatment starts with telling them apart.

These complaints are common, are usually mild, and often come and go over time. Research shows that many people improve with simple, reversible measures. A jaw that clicks without pain and without limiting opening is, in most cases, simply monitored.

Symptoms vary from person to person and often appear together:

• Jaw and facial pain: in front of the ear, at the temples or in the cheeks, often worse when chewing or on waking.
• Jaw clicking or popping: a click, or a grating sound, when opening or closing the mouth.
• Limited opening: not being able to open as wide as before, or the jaw drifting to one side as it opens.
• Locking: the jaw briefly catching in an open or closed position.
• Head, neck and ear-area pain: particularly tension-type headaches around the temples, or a feeling of fullness in the ear despite a normal ear examination.
• Tooth wear and sensitivity: flattened biting edges, enamel cracks, broken fillings or crowns, sensitivity near the gum line.
• Grinding noises at night: usually noticed by a partner, together with stiff jaw muscles in the morning.

Bruxism means involuntary clenching or grinding of the teeth, or bracing the jaw in one position. Current international consensus describes bruxism not as a disease in itself but as a muscle activity that can also occur in healthy people. What matters is whether it is causing harm to the teeth, muscles or joints.

For daytime clenching, the key step is learning the jaw’s resting position: when your lips are closed, your teeth should not be touching. Checking a few times a day – ‘are my teeth touching right now?’ – helps many people become aware of the habit. Sleep bruxism cannot be controlled at will, so the priority is protecting the teeth and any restorations.

TMJ disorders and bruxism are, in most cases, multifactorial. Biological, psychological and behavioural factors combine, which is why two people with the same risk factors may have very different experiences.

• Stress and anxiety: strongly linked with daytime clenching; they can increase muscle tension and how pain is felt.
• Sleep: sleep bruxism is associated with brief arousals during sleep. If snoring or pauses in breathing are suspected, a sleep medicine assessment becomes important.
• Habits: constant gum chewing, nail biting, pen chewing, holding a phone between shoulder and jaw, chewing on one side.
• Lifestyle and medication: caffeine, alcohol, smoking and some medicines (for example, certain antidepressants) can increase bruxism. Medication should only be changed by the prescribing doctor.
• Trauma: a blow to the jaw, or procedures that require the mouth to stay open for a long time.
• General health: widespread musculoskeletal pain, some rheumatological conditions and joint hypermobility.

What role does the bite (occlusion) play?

For many years, an uneven bite was thought to be the main cause of TMJ problems. Current evidence does not support this view. The bite can be one contributing factor in some people, but it is rarely the sole cause. For that reason, grinding down teeth (occlusal adjustment), orthodontics or extensive crowns purely to treat jaw pain are not recommended as a first-line treatment.

Bite analysis still matters – but for different reasons. A prosthodontist examines the bite to understand the pattern of tooth wear, to adjust a splint accurately, and to plan future crowns, bridges or implant-supported prostheses so that they can cope with heavy forces.

The assessment starts with a detailed conversation: where the pain is, when it started, what time of day it is worse, whether there is clicking or locking, how you sleep, your stress levels, general health and any medicines you take. A clinical examination follows:

• Muscle and joint palpation: the chewing and temple muscles and the joint area are examined with gentle pressure; tender points and patterns of referred pain are noted.
• Range of motion: mouth opening is measured in millimetres, along with side-to-side and forward movements and any deviation as the jaw opens.
• Joint sounds: the presence and timing of clicking or grating are assessed.
• Teeth and bite analysis: wear facets, cracks, the condition of existing fillings and crowns, and how the teeth meet. Where useful, a digital intraoral scan can record the teeth so that wear can be compared over time.
• Ruling out tooth and gum causes: decay, a cracked tooth or gum inflammation can mimic jaw pain; where needed, this is assessed together with a periodontist.

Is imaging needed?

Not everyone needs imaging. A panoramic X-ray gives a general overview of the teeth and jaws. If bony changes in the joint are suspected, a cone-beam CT (CBCT) may be requested; if information about the disc and soft tissues is needed, an MRI may be advised. These decisions depend on the examination findings and on whether imaging would actually change the treatment plan.

When is a referral to another specialist needed?

Jaw pain sits where several specialities meet. Depending on the findings, a referral may be suggested to:

• Physiotherapy: for muscle pain, restricted movement and neck or posture problems – exercises and manual therapy.
• ENT (ear, nose and throat): for ear pain, fullness, ringing or hearing changes, to rule out ear-related causes.
• Oral and maxillofacial surgery: for advanced structural joint changes, repeated locking, or situations that need a surgical opinion.
• Neurology: for frequent headaches, migraine features, facial numbness or suspected nerve pain.
• Sleep medicine: when snoring, pauses in breathing or excessive daytime sleepiness are present.
• Psychiatry or psychology: when chronic stress, anxiety or sleep problems are clearly driving the symptoms.

International guidelines agree that treatment should start with conservative, reversible measures. These do not permanently change the teeth or the joint and can be stopped or adjusted as symptoms settle. For most people, a suitable combination of them is enough.

1. Information and reassurance: understanding how the problem develops – and that it is usually benign – can reduce anxiety and the muscle tension that goes with it.
2. Self-care: a softer diet during painful spells; avoiding large bites and chewing gum; short applications of warmth or cold; resting the jaw; and awareness of daytime clenching.
3. Splint (night guard) therapy: a custom hard stabilisation splint protects the teeth overnight and may reduce muscle pain in some people.
4. Physiotherapy: jaw and neck exercises, manual therapy and posture advice.
5. Medication: if painkillers, muscle relaxants or other medicines are needed, they should be prescribed by a physician, for a limited period and with follow-up. Long-term self-medication is not advised.
6. Stress management and sleep hygiene: regular sleep, less caffeine and alcohol in the evening and, where helpful, psychological support.

Progress is reviewed after a few weeks to a few months. If improvement is less than expected, the diagnosis is reconsidered and further assessment is planned with the relevant specialists. Surgery is considered only for specific structural problems that have not responded to conservative care.

A splint is a clear, removable appliance that fits over the teeth – often called a night guard. Not all guards are the same, and the type matters.

It is worth being clear about what a splint can and cannot do. A splint does not stop bruxism. Even if the muscles stay active, it directs the force onto the splint rather than the teeth, aiming to reduce wear and fractures. Its effect on jaw pain varies: some people notice clear relief, others only a modest change. That is why a splint is used alongside the other conservative measures rather than on its own.

A custom splint is made from a conventional impression or a digital scan. At the fitting appointment its seating and bite contacts are checked; a short period of getting used to it is normal. Clean the splint after each use, keep it in its case, and bring it to your review appointments.

Botulinum toxin (often called ‘jaw Botox’) is injected into the chewing muscles to temporarily reduce the strength of their contraction. Research into its use for bruxism and muscular jaw pain is ongoing; the current evidence is mixed, and its long-term effects, including possible effects on muscle and bone, are still debated.

This treatment is outside the scope of prosthodontics and is not offered as a recommendation on this page. Anyone considering it should discuss the possible benefits and risks in detail with a physician qualified in this area. Even after such injections, a splint may still be needed to protect the teeth from wear at night.

Bruxism is one of the most important risk factors for ceramic and porcelain restorations. Undetected grinding can lead to chipping or debonding of veneers, wear of natural teeth opposite zirconia crowns, and screw loosening or component fractures in implant prostheses.

So before planning smile design or fixed prosthetics such as zirconia crowns and veneers, a prosthodontist looks for answers to these questions:

• Are there signs of active clenching or grinding, and a clear pattern of wear?
• Are the jaw joints and muscles settled? If there is pain, that phase is managed first.
• Are the chosen material and restoration thickness suited to the expected forces?
• Will a night splint be needed afterwards to protect the new restorations?

Grinding does not usually rule out smile design – but the plan needs to take it into account. Dr. Maryam Fazeli includes bite and jaw joint assessment as a routine part of prosthodontic planning, alongside the aesthetic evaluation.

Most jaw pain is not an emergency. However, seek medical advice promptly if you notice:

• Suddenly being unable to close your mouth (the jaw stuck open)
• Mouth opening becoming rapidly and progressively smaller
• Swelling, redness or fever in the face or jaw
• Numbness or tingling in the face, lips or tongue, or weakness of the facial muscles
• Hearing loss, discharge from the ear or dizziness
• Jaw pain after a blow or accident, or your teeth no longer meeting as before
• Unexplained weight loss, or worsening pain that wakes you at night
• New temple pain after the age of 50, with the jaw tiring quickly when chewing
