TMJ Disorder vs. Trigeminal Neuralgia
TMJ pain is musculoskeletal and tied to jaw movement; trigeminal neuralgia is electric, lightning-like nerve pain triggered by light touch or cold air.
Key Facts
- TMJ pain worsens with chewing, clenching, or wide opening
- Trigeminal neuralgia produces brief electric-shock attacks
- Trigger zones (light touch on face) are classic for trigeminal neuralgia
- MRI is often used to rule out vascular compression of the trigeminal nerve
TMJ Disorder
Temporomandibular joint disorder involves the joint, disc, and muscles of mastication. Pain is dull, aching, and reproducible with palpation or function.
Trigeminal Neuralgia
Trigeminal neuralgia is paroxysmal, severe, electric pain in one or more trigeminal divisions, often triggered by chewing, brushing, wind, or shaving.
Why People Confuse Them
Both produce facial pain, often unilateral. But TMJ is musculoskeletal and constant; neuralgia is neurologic and explosive.
