- TMJ syndrome arises when the jaw joint, chewing muscles and bite no longer work in harmony.
- Signs include jaw clicking, pain when chewing, morning jaw tension and headaches.
- Common triggers are clenching, teeth grinding, stress, bite irregularities and injury.
- Treatment ranges from self-care and oral splints to physiotherapy and, rarely, surgery.
Pain in the jaw joint often starts quite slowly. At first you may only notice that your jaw clicks when you open your mouth. Later, chewing can become uncomfortable, and in the morning you may wake up feeling that your jaw is tense, tired or tight. Some people also experience headaches, pain around the ear or a feeling of pressure in the temples.
This is exactly why it is not always immediately clear where the problem is coming from. The pain can feel like a toothache, an ear problem or tension in the facial muscles, when in reality it may be linked to the jaw joint.
Problems with the jaw joint arise when the joint, the chewing muscles and the bite no longer work in harmony. Common causes are clenching, teeth grinding, stress, bite irregularities, injury or overloading of the jaw.
If the pain keeps coming back, if the jaw clicks frequently or if you find it hard to open your mouth, an examination is advisable. Such problems can escalate over time, so it is better to check them earlier rather than only when they start to seriously interfere with eating, speech or sleep.
Description and prevalence of the syndrome
TMJ syndrome can occur in any age group, although it is more common in young adults. Symptoms range from mild to severe and can occur occasionally or become chronic. In some cases the syndrome causes permanent damage to the jaw joint. Research shows that jaw joint problems are more common in women than in men, although the exact reason for this difference is not entirely clear.
Psychological factors in the problem
Psychological factors such as stress and anxiety can be important reasons for jaw joint pain. Stress can cause unconscious teeth grinding or clenching, which places additional strain on the jaw joint and jaws. Psychological support and stress-management techniques are key in treating and relieving the symptoms of the syndrome.
Causes of chronic pain
Chronic jaw joint pain is often the result of a combination of physical and psychological factors. Physical causes include jaw joint injuries, arthritis, bite irregularities and tooth wear. Psychological factors such as prolonged stress, anxiety and depression can also contribute to the development and persistence of pain.
Different types of pain
Pain can be divided into several types, including pain in the muscles that control jaw movement, and pain that directly affects the jaw joint. Muscle pain is often the result of overloading or tension, while joint pain can stem from inflammation, degenerative changes or injury. Distinguishing between these types is key to guiding treatment.
Diagnosis and treatment
Diagnosing jaw joint pain requires a comprehensive approach that includes a physical examination, a history of the symptoms and, in some cases, imaging such as X-rays. Treatment focuses on relieving symptoms and restoring joint function, and can include oral splints, physiotherapy, lifestyle changes and, in some cases, medication or even surgery. The NHS notes that jaw joint problems (TMD) often improve with simple self-care and treatments.[NHS]
Accurate diagnosis is important
In diagnosis, accurately identifying the symptoms and their causes is key. This includes assessing the range of jaw movement, identifying points of pain in the joint and analysing the bite. Imaging such as MRI and CT can help assess the condition of the jaw joint, muscles and surrounding tissues. An accurate diagnosis is the foundation for successful treatment.

What can you do yourself when your jaw joint hurts?
If the pain is not severe and has appeared recently, you can rest the jaw for a few days. This does not replace an examination, but it can help reduce irritation of the joint and muscles.
It can help to:
- eat softer food for a few days,
- avoid chewing gum,
- not bite your nails, pencils or hard foods,
- not force your mouth open,
- observe whether you clench your teeth during the day,
- try to relax the jaw so that the upper and lower teeth do not touch,
- apply a warm compress to the chewing muscles when there is tension.
If the pain does not settle, if the jaw locks or if you have trouble opening your mouth, an examination is needed.
Is jaw clicking a cause for concern?
Jaw clicking is not always dangerous. In some people it occurs occasionally and without pain. In such cases it is usually not a serious problem.
It is different if the clicking occurs together with pain, a feeling of locking, difficulty opening the mouth or muscle tension. In that case it can be a sign that the joint disc, muscles or bite are not working entirely in harmony.
It is advisable to book an examination if:
- the jaw clicks almost every day,
- the jaw locks,
- you have trouble opening your mouth,
- you feel pain when chewing,
- the pain spreads towards the ear or head,
- you wake up in the morning with a tense jaw.
The difference between muscle and joint pain
Distinguishing between pain that originates in the muscles and pain that originates in the jaw joints themselves is important for a correct diagnosis and treatment. Muscle pain is often linked to tension and overloading, while joint pain can stem from inflammation, wear or structural anomalies. This distinction allows for more targeted treatment.
Which types of orofacial pain are there?
Trigeminal neuralgia: symptoms and treatment
Trigeminal neuralgia is another form of orofacial pain that affects the trigeminal nerve, responsible for the sensory and motor function of the face. Symptoms include sharp, stabbing pain in the face that can last from a few seconds to a few minutes and can also cause a headache. Treatment often focuses on relieving pain with medication.
Phantom pain in the oral cavity
Phantom pain in the oral cavity is a phenomenon in which individuals feel pain or discomfort in an area where teeth have been removed or where there are no longer any dental structures. This type of pain can be very disruptive, as it is difficult to diagnose and treat. Phantom pain can arise from changes in the nerve pathways resulting from tooth removal or nerve damage.
Understanding and treating phantom pain
Treatment of phantom pain usually focuses on relieving symptoms and improving the patient’s quality of life. Methods can include medication such as antidepressants and anticonvulsants, which can help manage pain signals. Psychological techniques such as counselling and cognitive behavioural therapy are also often used to help cope with the emotional aspects of pain.
Burning mouth syndrome
Burning mouth syndrome (glossodynia) is a condition in which individuals experience a burning sensation, tingling or pain in the mouth without an obvious physical cause. It is often linked to psychological factors such as stress and anxiety, and can affect overall quality of life. Diagnosing glossodynia can be challenging, as the symptoms are subjective and there are no visible signs of disease.
Treatment of burning mouth syndrome is aimed primarily at relieving symptoms and involves various approaches, such as dietary changes, the use of special oral gels or rinses, and stress management. In some cases, medication that relieves pain or the burning sensation can also help.
Jaw relaxation exercises
For mild jaw joint problems, gentle exercises can help relax the chewing muscles, improve joint mobility and reduce the feeling of tension. It is important to perform them slowly, without force and only up to the point where you feel no pain – the exercises are not meant to work through the pain. They are best done in front of a mirror and during a period when the jaw is not acutely painful. If any exercise worsens the pain or causes locking, stop it.
It can help to do the following:
- Relaxed mouth opening: rest your tongue gently on the palate behind the upper incisors and slowly open and close your mouth without moving the tongue away. Repeat 5–10 times.
- Controlled opening with the hand: slowly open your mouth as far as is comfortable and gently support the chin with two fingers. Hold for a few seconds and slowly close.
- Side-to-side movements: gently move the lower jaw left and right, without straining, a few repetitions in each direction.
- Forward and backward movement: slowly push the lower jaw slightly forward and then back into a relaxed position.
- Relaxing the chewing muscles: consciously check whether you are clenching your teeth; relax the jaw so that the upper and lower teeth do not touch, while the lips stay closed.
- Warm compress: before the exercises, apply a warm compress to the chewing muscles for a few minutes to relax them.
Do the exercises a few times a day, each only a few repetitions. Their purpose is relaxation, not tiring the muscles. If clicking, pain or jaw locking do not settle despite regular practice, the exercises do not replace an examination – in that case it is advisable for a dentist or specialist to assess the condition of the jaw joint.
A multidisciplinary approach to treatment
Treating TMJ syndrome often requires a multidisciplinary approach involving dentists, physiotherapists, pain-management therapists and, in some cases, psychologists. This integrated approach allows comprehensive treatment of both the physical and psychological aspects of jaw joint problems. Physiotherapy, for example, can help relieve muscle tension, while psychotherapy can help manage the stressors that contribute to symptoms.
The importance of preventive action
Preventive measures such as regular dental check-ups, proper oral hygiene, avoiding harmful habits like teeth grinding, and using tooth guards during sleep are key to preventing the development or worsening of symptoms. Timely action and awareness of possible triggers can significantly reduce the risk of long-term jaw joint problems.
Advanced methods of treating the jaw joint
For patients with more severe forms of TMJ syndrome, advanced treatment methods such as arthrocentesis and arthroscopy are available. Arthroscopy is a more complex procedure in which a small camera and instruments are used to examine and treat the inside of the joint. Both procedures are performed on an outpatient basis and offer faster recovery compared with traditional open surgery, and are aimed at improving joint mobility and relieving pain.
Comprehensive management of TMJ syndrome
Comprehensive management of TMJ syndrome requires a multidisciplinary approach that combines various treatment methods – from conservative approaches such as oral splints and physiotherapy to more advanced surgical procedures. Early recognition of symptoms and cooperation between the patient and the healthcare team are key to effective treatment and symptom management.

Frequently asked questions about TMJ syndrome
Why does my jaw joint hurt?
Jaw joint pain is often linked to overloading of the joint or chewing muscles. Common causes are clenching, teeth grinding, stress, bite irregularities, injury or prolonged tension in the jaw.
Why does my jaw click when I open my mouth?
Jaw clicking can occur when the jaw joint does not move entirely in harmony. If the clicking is only occasional and without pain, it is not always a cause for concern. However, if it occurs together with pain, jaw locking or difficulty opening the mouth, an examination is advisable.
Is jaw clicking dangerous?
Jaw clicking on its own is not necessarily dangerous. What matters is whether other signs are also present, such as pain, limited mouth opening, headaches, a feeling of a tight jaw or pain when chewing. In that case it is a good idea to check the condition of the jaw joint.
Why does my jaw hurt in the morning?
Morning pain or tension in the jaw is often linked to night-time clenching or teeth grinding. Many people do not even notice it because it happens during sleep. Signs can also include worn teeth, sensitive muscles, a headache or a feeling of a tired jaw.
Can stress cause jaw pain?
Yes. Stress is one of the common reasons for unconscious teeth clenching during the day or at night. This can strain the chewing muscles and the jaw joint, causing pain, tension, headaches or discomfort when opening the mouth.
When should I have an examination for the jaw joint?
Book an examination if the pain keeps coming back, if the jaw clicks frequently, if it locks or if you find it hard to open your mouth. It is also advisable if you have pain when chewing, frequent headaches, pain around the ear or morning tension in the jaw.
Can jaw joint problems cause headaches?
Yes. Tension in the chewing muscles and overloading of the jaw joint can present as a headache, especially in the temple area. In some people the pain spreads towards the ear, face or neck.
