Headache From Clenching Your Jaw? Here's What It Means and What to Do
Updated July 20261 minute read
Headaches from jaw clenching or grinding come from the powerful jaw and temple muscles being overworked — the pain is often felt at the temples or as a tension-type headache, sometimes worst in the morning if you grind at night. It's common, stress-linked, and manageable. Treatment combines clenching awareness, jaw and neck muscle work, stress strategies, and often a dental night guard, with physical therapy guiding the muscle and posture pieces.
What this usually means
Most likely causes. Overloaded jaw and temple muscles from clenching/grinding (often with neck tension) cause these headaches. Stress is a major driver. Less common causes. Other headache types (like migraine) can coexist; persistent or unusual headaches warrant assessment.
What you can try at home
Build awareness of daytime clenching and practice a relaxed jaw rest position (lips together, teeth apart). Reduce gum and hard/chewy foods, manage stress, and address neck tension and posture. A dental night guard helps if you grind at night.
When to see a physical therapist
If clenching-related headaches are frequent, a TMJ-focused PT can treat the jaw and neck muscles and reduce clenching.
Red flags — don't wait
Call emergency services for a sudden severe "worst-ever" headache or headache with neurological symptoms. Seek care for jaw pain with chest/breathing symptoms (emergency) or — over 50 — jaw pain with scalp tenderness and vision changes.
How a PT treats this
Treatment relaxes and retrains the jaw and neck muscles, improves posture, and reduces clenching.
