Have you ever noticed your jaw clicking when you yawn, chew or take a big bite of something? Perhaps your jaw feels tight first thing in the morning, or you catch yourself clenching your teeth while concentrating at work.
It’s surprisingly easy to overlook jaw tension until it starts interfering with everyday things like eating, talking or opening your mouth comfortably.
The good news is that jaw clicking and tightness don’t always mean something serious is wrong. However, when these symptoms become frequent, painful or start affecting how your jaw moves, it’s worth understanding what might be happening.
Why does my jaw click or feel tight?
Your jaw is connected to your skull by two small joints, one just in front of each ear. These are called the temporomandibular joints, often shortened to TMJs.
Place your fingers just in front of your ears and slowly open and close your mouth. You may be able to feel these joints moving.
They work together with the muscles around your jaw, face and neck to help you chew, speak, swallow and yawn.
Sometimes the joints or surrounding muscles become uncomfortable or don’t move as smoothly as usual. This can lead to symptoms known collectively as temporomandibular disorders (TMD).
TMD can cause jaw pain, clicking, stiffness, difficulty opening the mouth and occasionally discomfort around the ears or temples.
But there isn’t always one obvious cause.
What causes jaw clicking and tightness?
1. You may be clenching or grinding your teeth
Do you ever realise you’ve been pressing your teeth together while working, driving or concentrating?
Clenching and grinding your teeth is known as bruxism. It can happen during the day or while you’re asleep, sometimes without you realising.
Repeated clenching can place extra demands on the muscles responsible for moving your jaw. This may contribute to tenderness, fatigue or a feeling of tightness around your cheeks and temples.
Some people notice their symptoms are worse in the morning, particularly if they’ve been grinding their teeth overnight.
Stress and anxiety can contribute to bruxism, although they’re not the only possible factors.
What may help: Try noticing where your jaw rests throughout the day. When you’re not eating or speaking, your teeth should generally be slightly apart, with your jaw relaxed.
If you suspect you’re grinding your teeth at night, speak to your dentist. They can check for signs of tooth wear and discuss whether a protective mouthguard or other treatment is appropriate.
2. The joint may be making a clicking sound
Jaw clicking can happen when the small cartilage disc inside the temporomandibular joint moves slightly out of its usual position and then moves back as you open or close your mouth.
This disc normally helps the joint move smoothly.
If its movement changes, you may hear or feel a click, pop or occasional catching sensation.
Importantly, a clicking jaw isn’t necessarily a problem that needs treatment.
Many people experience painless jaw clicking without developing significant difficulties.
However, clicking accompanied by pain, locking or difficulty opening your mouth should be assessed.
3. Your jaw muscles may be overworking
Your jaw muscles are involved in far more than chewing meals.
They also help you speak, swallow and control your mouth movements throughout the day.
Chewing gum frequently, biting your nails, holding objects between your teeth or repeatedly eating particularly chewy foods can place additional demands on these muscles.
If your jaw is already sensitive, these activities may aggravate discomfort.
What may help: Give your jaw a temporary break from habits that make symptoms worse. Choose foods that are easier to chew during a flare-up, without unnecessarily restricting your diet for long periods.
4. Stress may be contributing to jaw tension
Think about what happens when you’re rushing to meet a deadline or dealing with a difficult situation.
You might tense your shoulders, hold your breath or tighten your jaw without noticing.
For some people, stress is associated with increased jaw clenching and muscle tension.
This doesn’t mean jaw pain is simply caused by stress or that the symptoms are imaginary. Jaw discomfort is real, and there can be several physical and behavioural factors involved.
However, recognising when you tend to clench your teeth may help you manage one possible contributor.
5. Your neck and jaw may be affecting each other
Have you noticed that jaw discomfort sometimes comes with a stiff neck or tension around your temples?
The muscles and nerves involved in jaw movement and neck function are closely connected.
Some people with TMD also experience neck pain or headaches.
This doesn’t necessarily mean poor posture is causing your jaw problem. The relationship is more complicated, and there’s limited evidence that any single sitting or sleeping position directly causes TMD.
However, when jaw and neck symptoms occur together, it may be helpful to assess both areas rather than focusing only on the jaw.
Why does my jaw click when I eat or yawn?
Opening your mouth widely requires your jaw joints to rotate and slide forwards.
If the disc inside one of the joints moves differently from usual, this movement can produce a clicking sound.
You might notice it when biting into an apple, yawning or chewing something particularly firm.
If the clicking is painless and your jaw moves normally, treatment may not be necessary.
But if you experience pain, repeated catching or difficulty opening your mouth, a dentist or appropriately trained healthcare professional can assess whether TMD or another problem may be involved.
What can I do to ease jaw tension?
There are several gentle things you can try at home, particularly if your jaw feels tight or tired.
Five simple ways to help your jaw relax
- Check whether you’re clenching
Throughout the day, notice whether your teeth are touching when you’re not eating.
Try allowing your teeth to separate slightly and letting your jaw rest comfortably.
- Apply gentle warmth
A warm compress against the side of your face for around 10 to 15 minutes may help ease muscle discomfort. Make sure it isn’t too hot.
Some people find a cool compress more soothing, so use whichever feels comfortable.
- Avoid overworking your jaw
If chewing makes your symptoms worse, temporarily avoid chewing gum, very tough foods and taking unusually large bites.
- Keep movements gentle
Continue using your jaw within a comfortable range rather than deliberately forcing it to open widely or repeatedly testing whether it clicks.
- Pay attention to stress-related habits
If you tend to clench your teeth when concentrating, try setting occasional reminders to relax your jaw.
Simple breathing or relaxation exercises may also help you notice and reduce unnecessary muscle tension.
If symptoms continue despite these changes, professional assessment can help identify the next steps.
Can physiotherapy help with jaw clicking and tightness?
Physiotherapy may be helpful for some people with temporomandibular disorders, particularly when symptoms involve muscle tension, restricted jaw movement or associated neck discomfort.
A physiotherapist with appropriate training in TMD assessment and management may look at:
- How comfortably and widely you can open your mouth
- Whether your jaw moves evenly
- Tenderness or tension in the muscles around your jaw
- Any associated neck symptoms
- Habits or activities that may aggravate discomfort
Depending on the findings, treatment may include gentle exercises, advice on reducing clenching, relaxation techniques and appropriate manual therapy.
The aim is to improve comfort and function, rather than simply trying to eliminate a clicking sound.
It’s important to check that your physiotherapist has experience treating jaw problems, as TMD management requires specific knowledge.
Can chiropractic treatment help with jaw tension?
Some people experience jaw discomfort alongside neck stiffness or other musculoskeletal symptoms.
In these circumstances, a chiropractor may be able to assess the neck and surrounding muscles to establish whether there are related problems that could benefit from conservative care.
Treatment might involve movement advice, exercises or appropriate hands-on techniques for associated neck discomfort.
If your main symptoms involve jaw clicking, locking, dental pain or difficulty opening your mouth, a dental assessment is generally the most appropriate starting point.
A chiropractor should refer you to a dentist or another suitably qualified professional where necessary.
When should I seek help for jaw clicking or pain?
Occasional painless clicking may not require treatment, but it’s sensible to arrange a dental assessment if:
- Your jaw pain persists or keeps returning
- You struggle to open or close your mouth comfortably
- Your jaw catches or locks
- Chewing or speaking becomes painful
- You regularly wake with jaw pain or suspect you’re grinding your teeth
- Your symptoms are affecting your eating or everyday activities
Seek urgent dental or medical advice if you develop significant facial swelling, fever, signs of infection or sudden severe pain.
If your jaw becomes stuck open or you cannot close your mouth, seek urgent medical assessment rather than trying to force it back into place.
Jaw pain following an injury, particularly with a change in your bite or difficulty moving your jaw, also needs prompt assessment.
A little attention to your jaw can make a difference
Jaw clicking and tightness can be easy to dismiss, especially when the symptoms come and go.
Sometimes, becoming more aware of clenching habits and making small changes to how you use your jaw can help reduce discomfort.
If the problem persists, understanding whether it’s related to the jaw joint, surrounding muscles or another cause is the best place to start.
At Luck’s Yard Clinic in Milford, Surrey, our team can help assess relevant musculoskeletal symptoms, including associated neck discomfort, and discuss whether physiotherapy or chiropractic care may be appropriate.
For symptoms centred on the jaw joint itself, your dentist is usually the best first point of contact.
