Understanding TMJ Dysfunction: Causes, Symptoms & Treatment

Your temporomandibular joints — the TMJs — sit just in front of each ear and connect your jaw to your skull. You use them thousands of times a day: every word, every meal, every yawn. So when one starts misbehaving, it doesn't stay quiet for long.

What is TMJ dysfunction?

TMJ dysfunction (often called TMD) is an umbrella term for problems affecting the jaw joint, its cartilage disc, and the muscles that power it. The joint itself is unusual — it both hinges and glides, with a small disc cushioning the movement. When the muscles become overworked, the disc slides out of rhythm, or the joint surfaces become irritated, the system loses its smooth coordination.

Common causes we see in NW Calgary

• Clenching and grinding (bruxism) — often stress-related, and often happening at night without you knowing
• Whiplash and head injuries — car accidents frequently injure the jaw alongside the neck
• Prolonged dental work — long periods with the mouth held wide open
• Postural strain — forward-head desk posture changes how the jaw rests and tracks
• Arthritic changes — the TMJ is a joint like any other and can develop arthritis
• Habits — gum chewing, nail biting, chewing on one side only

Symptoms that point to the TMJ

The obvious ones are jaw pain, clicking, and limited opening. The sneaky ones are why TMD goes undiagnosed for years: temple and forehead headaches, ear pain or fullness without infection, ringing in the ears, facial muscle tension, and even dizziness. Many of our patients have seen multiple providers for "ear problems" or "tension headaches" before anyone examines their jaw.

The neck connection

The upper neck and the jaw share nerve pathways and work as one mechanical system. Whiplash, poor posture, and upper-cervical stiffness all feed directly into jaw symptoms — which is why effective TMJ treatment almost always includes the neck.

The good news

TMD responds remarkably well to conservative care. Physiotherapy that combines hands-on treatment of the jaw and neck, motor-control retraining, and habit modification resolves or significantly improves most cases — no surgery required. If your jaw clicks, aches, or locks, or your "tension headaches" have never quite made sense, a TMJ assessment is a worthwhile place to start.
