Is Your Jaw Working Overtime?

Some forms of tension are obvious. Others sit quietly behind a laptop, in traffic or halfway through a difficult conversation. You may not notice that your teeth are pressed together until your jaw aches, your temples feel tight or somebody tells you that you grind your teeth at night.

Jaw pain has several possible causes, and clenching is only one of them. The useful first step is not to assume, but to notice when the jaw is working even though you are not eating or speaking.

Your teeth do not need to meet at rest

Many people are surprised by this. When the jaw is relaxed, the lips may be together but the upper and lower teeth are usually slightly apart.

Try checking at ordinary moments: reading an email, waiting for a page to load, cooking or watching television. If your teeth are touching, let the lower jaw soften without forcing it down. Think of creating a little space rather than performing a stretch.

You might also notice habits that keep the jaw busy:

• chewing gum for long periods
• biting nails, pens or the inside of the cheek
• holding the phone between shoulder and ear
• bracing the jaw while lifting or concentrating
• drinking a lot of caffeine late in the day if it affects your tension or sleep

The aim is not to monitor yourself every minute. A few calm check-ins can make an automatic habit easier to spot.

When the jaw is sore

Temporomandibular disorder, usually shortened to TMD, describes problems affecting the movement of the jaw. Symptoms can include pain around the jaw, ear or temple, clicking, difficulty opening the mouth and headaches around the temples.

Simple measures may help during a mild flare. NHS guidance suggests softer food for a while, avoiding gum and very wide opening, and trying wrapped heat or cold—whichever feels better. Gentle massage of sore jaw muscles may also feel comforting.

Avoid aggressive self-treatment or repeatedly testing a click. A sound without pain is different from a jaw that locks, will not open properly or makes eating difficult.

Start with the right professional

See a dentist if you grind your teeth, have tooth sensitivity or damage, or have pain in the jaw, face or ear. A dentist can check the teeth and bite and discuss whether a properly fitted mouth guard is appropriate. A GP can help when stress, anxiety, medication or sleep problems may be contributing.

Seek urgent advice through NHS 111 if the jaw locks, you cannot eat or drink, you have difficulty opening your mouth, or pain occurs with severe headaches, scalp tenderness or changes in vision.

Think beyond the jaw, without blaming posture

Jaw tension can arrive alongside a raised shoulder, held breath or long spell of concentration. That does not mean one “bad posture” has caused everything. It can simply be useful to let the whole body change position: put both feet down, loosen your grip on the mouse, breathe out fully and look away from the screen.

Massage, acupuncture or hands-on care may be part of a wider plan for some people, but should not replace a dental or medical assessment where one is needed. At Bonn Square Therapy Room, we will ask about the wider pattern and be clear if another professional is the better first step.
