TMJ & jaw pain: why it happens and how physiotherapy fixes it
A jaw that clicks when you eat, aches by the end of the day, or gets stiff and tender near the ear, that's often TMJ. It's one of the most common problems we treat that people never realise a physiotherapist can help with. Most reach for painkillers or a dentist and never hear that the muscles doing the damage can be retrained.
What "TMJ" actually means
The TMJ (temporomandibular joint) is the hinge that connects your jaw to your skull, just in front of each ear. When that joint and the muscles around it stop working smoothly, the result is called TMD: temporomandibular disorder. Most people just say "TMJ" for both. The good news: the large majority of cases are muscular and mechanical, not structural, which means they respond well to the right treatment.
Signs you might have a TMJ problem
- Pain or tenderness in the jaw, cheek, or in front of the ear
- Clicking, popping, or grating when you open or close your mouth
- Jaw that feels stiff, tired, or occasionally locks open or closed
- Headaches around the temples, or a dull ache that spreads to the neck
- Ear symptoms with no infection: fullness, pressure, or ringing
- Waking with a sore, tight jaw (a classic sign of night grinding)
What causes it
- Clenching & grinding (bruxism): usually stress-driven and often happening at night without you knowing. The single most common driver.
- Neck & posture: hours hunched over a phone or laptop pull the head forward and overload the jaw muscles. (If that's you, our desk-posture guide tackles the same root problem.)
- Habits: chewing gum, biting nails, or always chewing on one side.
- Bite or dental issues: how your teeth meet can load the joint unevenly.
- Trauma or arthritis: a blow to the jaw, or joint wear over time.
How physiotherapy treats TMJ
Because most jaw pain is muscular, it's very treatable without drugs or surgery. A focused plan usually combines:
- Hands-on release of the tight jaw, cheek, and neck muscles that refer pain into the face and head
- Joint mobilisation to restore smooth, even jaw movement and reduce clicking
- Targeted jaw-control exercises that retrain the muscles to open and close in a balanced way
- Posture & neck work: because the jaw and neck share muscles, fixing forward-head posture takes real load off the joint
- Habit coaching: becoming aware of daytime clenching, and practical ways to break it
When night grinding is a big factor, we'll often work alongside your dentist: a night guard protects your teeth while physiotherapy calms the muscles and joint that are actually generating the pain.
Simple things you can try today
- Find the rest position: tongue gently resting on the roof of your mouth, teeth slightly apart, lips together. Your teeth should only touch when eating.
- Notice clenching: set a phone reminder a few times a day: are your teeth touching? Unclench and drop the jaw.
- Go soft for a few days: smaller bites, softer foods, and skip the gum while things settle.
- Warmth: a warm compress on the jaw muscles for 10 minutes can ease tightness.
- Check your screen posture: bring the phone up to eye level and stop craning your neck forward.
These help many people take the edge off, but if the pain keeps coming back, that's a sign the underlying muscle and movement pattern needs proper attention. At FixUrMotion we assess your jaw, neck, and posture together and build a step-by-step plan, in the clinic or at home anywhere in Beirut.
When to get it checked
See a professional if your jaw locks and you can't fully open or close it, if pain is severe or getting worse, if it follows an injury, or if chewing and talking are affected. Sudden facial weakness or numbness is a medical emergency and needs urgent care, not physiotherapy. For everything else, an early assessment usually means a faster, simpler recovery.
