TMJ Disorder: Why Your Jaw Clicks and What Actually Fixes It
Quick answer: TMJ disorder causes jaw pain, clicking, limited opening, and often referred headache or neck pain. Most cases are muscle-driven (tension, clenching, grinding) and respond to physiotherapy within 6-8 weeks. A smaller group has a disc displacement inside the joint itself - also treatable without surgery in the majority of cases. Splints, injections, and surgery are reserved for the minority who don't respond.
What TMJ disorder looks like
- Jaw pain on one or both sides, worse with chewing or wide opening
- Clicking or popping on opening or closing
- Limited opening - normal is 40-50 mm between upper and lower incisors; under 35 mm limits eating a burger
- Locking - open lock (can't close) or closed lock (can't open fully)
- Referred pain - temples, behind the eye, ear (often mistaken for an ear infection), neck
- Worse in the morning if you grind at night, or worse by evening if you clench during stress
Three kinds of TMJ issue
1. Myofascial pain (most common - 60-70%)
Chronic tension in the masseter, temporalis, and pterygoid muscles from clenching, grinding (bruxism), chewing one-sided, or stress. No structural damage. Treatment: manual release, dry needling, posture retraining, sleep hygiene, and stress management. Expect noticeable improvement within 2-3 sessions.
2. Disc displacement with reduction
The articular disc sits between the jaw condyle and the skull. If it slides forward, opening the mouth forces the condyle to jump under it - the audible click. Click is louder on opening than closing, and there's often a second click on closing. Painless clicking is not necessarily a problem; painful clicking needs assessment. Treatment: jaw retraining exercises, controlled opening drills, and posture work.
3. Disc displacement without reduction (closed lock)
The disc is stuck forward and the condyle can't get under it - the jaw won't open past about 25-30 mm. Often follows a period of painful clicking that suddenly stops. Early physiotherapy (within 6 weeks) has good success rates for unlocking it manually and restoring range.
What physiotherapy looks like
Assessment covers opening range, deviation, clicking location, muscle tenderness, bite, posture (especially forward head), and cervical spine involvement. Up to 50% of TMJ patients have a cervical contribution.
Treatment typically combines:
- Manual therapy - jaw joint mobilisation, intra-oral muscle release (gloved finger inside the mouth to release masseter/pterygoid), cervical spine work
- Exercise - controlled opening, tongue-up-to-palate opening, resistance exercises, isometric holds
- Posture retraining - forward head posture shortens the suprahyoids and pulls the jaw back, compressing the joint
- Self-care - soft diet during flare, no gum, no nail biting, awareness of daytime clenching
Home programme is crucial - jaw disorders respond to frequent short bouts more than occasional long sessions.
When to consider splints or dentistry
A flat occlusal splint worn at night is useful for heavy night grinders - it doesn't stop grinding, it protects the teeth and offloads the joint. Your dentist makes it. Some people get Botox to the masseters - effective for grinding but doesn't address the underlying cause. Surgery is genuinely a last resort; arthrocentesis (lavage) or arthroscopy is considered only after ≥3 months of well-delivered conservative care.
What doesn't help
- Chewing gum to "strengthen" the jaw - it overloads it
- Wide opening stretches without control - can worsen a disc problem
- Painkillers alone - mask, don't fix
- "Jaw popping" yourself back into place - not a thing
