What Is Jaw Pain?
Jaw pain is any ache, stiffness, or discomfort in the jawbone or the area around the ears. It is a common condition that can range from mild to severe and can affect the ability to eat, speak, yawn, and sleep. While TMJ disorder is the most common cause, jaw pain can result from many different conditions, which makes an accurate diagnosis important.
Common Jaw Pain Symptoms
- Aching or throbbing pain in the jaw or face
- Jaw stiffness or limited range of motion
- Clicking or popping sounds when opening or closing the mouth
- Jaw locking open or closed
- Pain when chewing, yawning, or speaking
- Pressure or fullness in the ear
- Tension-type headaches radiating from the jaw
- Swelling on one or both sides of the face
- Tooth sensitivity or changes in bite
What Causes Jaw Pain?
Jaw pain rarely has a single cause. It can stem from the joint itself, the muscles around it, dental issues, or referred pain from other parts of the body.
TMJ disorder is the most common cause and affects the jaw joint and surrounding muscles. See our dedicated TMJ symptoms page for more detail.
Teeth grinding (bruxism) places repetitive pressure on the joint and muscles and is especially common during sleep or periods of high stress.
Stress and jaw clenching cause chronic muscle tension in the jaw, face, and neck that builds over time.
Arthritis, including both rheumatoid and osteoarthritis, can affect the jaw joint and cause stiffness and pain.
Dental problems such as a tooth abscess, gum disease, cracked teeth, or misalignment can radiate pain directly into the jaw.
Sinus infection causes inflammation in cavities that sit close to the jaw joint, creating pressure that feels like jaw pain.
Jaw injury or trauma from falls, sports injuries, or accidents can cause direct damage to the jaw joint or surrounding bones.
Nerve conditions such as trigeminal neuralgia cause sharp, shooting pain in the jaw and face.
Jaw Pain on One Side
One-sided jaw pain is very common. It can indicate muscle tension from clenching or poor posture, a tooth infection or dental issue on that side, jaw joint misalignment, or sinus pressure affecting one side more than the other. One-sided pain lasting more than a week should be professionally evaluated.
Jaw Pain and Headaches
Jaw pain and headaches are closely connected. The jaw muscles and neck muscles share nerve pathways, so when jaw muscles are tense or the joint is inflamed, pain can radiate upward and cause tension headaches or facial pain. Patients with chronic jaw pain frequently report recurring headaches. See our headache and migraine treatment page for more information on related conditions we treat.
Jaw Pain and Ear Pain
The jaw joint sits directly in front of the ear canal. When inflamed or misaligned, it can cause referred pain, pressure, or a feeling of fullness in the ear that is often mistaken for an ear infection. Patients also frequently report dizziness and balance issues alongside jaw and ear pain, as the jaw joint sits close to the vestibular system. See our dizziness treatment page for more information.
Jaw Pain from Stress
Stress is one of the most common but overlooked causes of jaw pain. When stressed, many people unconsciously clench their jaw or grind their teeth, especially during sleep. Over time this creates muscle fatigue, joint strain, and chronic jaw pain. Managing stress is a key part of treatment and is central to the approach at Moore MyoWorx.
Warning Signs: When Is Jaw Pain Serious?
Seek emergency care immediately if:
- Jaw pain spreads from the chest or shoulders, which may indicate a heart attack
- The jaw is locked open or closed
- There is visible swelling with fever, which may indicate infection
- Jaw pain follows a fall or injury, which may indicate fracture or dislocation
Contact a healthcare provider if jaw pain lasts more than one week without improvement.
When to See a Specialist for Jaw Pain
If jaw pain lasts more than a week, worsens over time, or affects eating and sleeping, it is time to seek professional evaluation. At Moore MyoWorx in Guelph, we take a neuromuscular approach to jaw pain, identifying the root cause rather than just managing symptoms.

Frequently Asked Questions
What are the most common symptoms of jaw pain?
What does jaw pain on one side mean?
Can stress cause jaw pain?
However, jaw pain can also increase stress, creating a vicious cycle. Tightness in the jaw and neck muscles may trigger more clenching and teeth grinding, which further worsens the pain. That’s why we take a different approach, addressing both the tension and the underlying cycle for more effective, long-lasting relief.
