The Most Common Causes of TMJ Disorders (TMD)
What's Behind Your Jaw Pain, Clicking, or Locking?
TMJ disorders (TMD) don't just happen randomly — they're often the result of underlying mechanical stress on the jaw joint, muscles, or teeth.
In my practice, I most often see two main causes: bruxism and bite imbalance. These issues can lead to pain, clicking, and even jaw locking if left unaddressed.
Understanding what's behind your symptoms is the first step toward lasting relief — and we'll explore that together.
How Bruxism Can Trigger TMJ Disorders
Bruxism is the unconscious habit of grinding or clenching your teeth — usually during sleep, but sometimes during the day as well.
In this video, I show how bruxism — teeth grinding — can lead to TMD, a disorder of the jaw joint.
My goal is to help you understand what's happening beneath the surface — and why early diagnosis matters.
While it may seem harmless at first, repeated pressure on your jaw joint can cause:
- Chronic tension in the jaw muscles
- Pain in the temples, neck, or face
- Damage to the teeth (wear, cracks, or flattening)
- Inflammation of the TMJ
- Changes in bite and jaw alignment
- Jaw stiffness or locking in severe cases
Bruxism is often linked to emotional stress, poor sleep quality, or an imbalanced bite.
In many cases, the muscles stay in a constant state of tension — even when you're not aware of it.
Over time, this strain can affect not only your jaw, but your posture and overall well-being.
Early evaluation can prevent long-term joint damage and help restore comfort and function.
I often diagnose bruxism in patients who aren't even aware they're doing it — until the joint pain begins. Early detection makes a big difference.
When the Bite Is Off, the Joint Takes the Stress
Your bite is meant to distribute pressure evenly across your teeth and jaws.
I take you beyond the surface to show how misaligned teeth and bite problems can silently overload your TMJ.
While symptoms may seem mild at first — like occasional clicking or muscle tension — the underlying imbalance can lead to progressive joint damage if left untreated.
When your bite (occlusion) is unbalanced due to:
- Crowded or rotated teeth
- Missing teeth
- Overbite, underbite, crossbite
- Jaw misalignment
…it can lead to:
- Overload on one side of the TMJ
- Muscle fatigue or spasm
- "Compensating" chewing patterns
- Wear and shifting of teeth
- Long-term joint damage and disc displacement
I don't just look at teeth — I evaluate how they function together with the muscles and joints. Even subtle misalignments can lead to years of discomfort.
