Jaw Pain on One Side? Here's What It Means and What to Do
Updated July 20261 minute read
One-sided jaw pain is usually a TMJ problem on that side — joint or disc irritation, or overworked jaw muscles from chewing mainly on one side or clenching. It can also be referred from the neck. It's typically manageable with jaw care and physical therapy. Always rule out a dental cause with a dentist, and treat jaw pain with chest pressure or breathlessness as a medical emergency.
What this usually means
Most likely causes. TMJ dysfunction or muscle tension on one side, often from one-sided chewing, clenching, or a disc issue. Neck-related (cervicogenic) pain can be one-sided too. Less common but important. A dental problem (tooth/abscess) on that side, or rarely referred cardiac pain (often left side), can cause one-sided jaw pain.
What you can try at home
Try to chew on both sides evenly, avoid gum and hard/chewy foods, practice a relaxed jaw rest position, and address neck tension and posture. See your dentist if a tooth seems involved.
When to see a physical therapist
For one-sided TMJ or muscle pain, a TMJ-focused PT can treat the joint, muscles, and neck contributors.
Red flags — don't wait
Call emergency services for jaw pain with chest pressure, breathlessness, or arm pain. Seek care for facial swelling with fever (dental infection), jaw pain after trauma, or — over 50 — jaw pain with scalp tenderness and vision changes.
How a PT treats this
Treatment addresses the jaw joint and muscles on the affected side, plus neck and posture contributors.
