Frequent headaches or migraines aren’t always caused by stress or eye strain; your jaw joint could be the real problem. The Temporomandibular Joint (TMJ) connects your jaw to your skull, and when it’s misaligned or overworked, it can trigger pain that radiates to the temples, forehead, ears, and neck. Teeth grinding, jaw clenching, poor posture, or bite issues often worsen TMJ disorders. Common signs include jaw pain, clicking sounds, facial soreness, and difficulty opening your mouth. Treating the jaw joint through dental care, night guards, physiotherapy, or stress management can significantly reduce headache frequency and improve overall comfort.
Constant Headaches and Migraines? It’s Probably Your Jaw Joint.

Do you experience frequent headaches or migraines that just won’t go away, even after taking painkillers or changing your routine? Many people assume headaches are caused by stress, lack of sleep, eye strain, or sinus issues. While these can be triggers, there is one commonly overlooked cause that often goes undiagnosed: your jaw joint.
At Summit Dental Clinic, we often see patients who have suffered from chronic headaches for years, only to discover that the real problem lies in their jaw joint, also known as the TMJ.
What Is the Jaw Joint (TMJ)?
The Temporomandibular Joint (TMJ) is the joint that connects your lower jaw (mandible) to your skull. You have one joint on each side of your face, just in front of your ears.
This joint allows you to:
Talk
Chew
Yawn
Swallow
Open and close your mouth smoothly
Because the TMJ is one of the most complex joints in the body, even small problems can lead to discomfort and pain in nearby areas, including the head, face, neck, and shoulders.
How Can Jaw Joint Problems Cause Headaches?
Jaw joint disorders (often called TMD or TMJ disorders) can place constant strain on the muscles and nerves around the head and face.
Here’s how it happens:
Jaw misalignment stresses facial muscles
Overworked jaw muscles become tense and inflamed
Nearby nerves get irritated
Pain radiates to the temples, forehead, eyes, or back of the head
This pain is often mistaken for:
Tension headaches
Migraines
Sinus headaches
According to studies, up to 60% of people with chronic headaches also show signs of jaw joint dysfunction, even if they don’t have jaw pain initially.
Healthy gums help reduce chronic inflammation, which is important for protecting heart health.
Common Signs Your Headache May Be Coming From Your Jaw
You may want to consider a jaw-related cause if your headaches are accompanied by:
Pain near the temples or ears
Clicking or popping sounds while opening the mouth
Jaw stiffness, especially in the morning
Pain while chewing or yawning
Locking of the jaw
Facial pain or pressure
Neck or shoulder tightness
Headaches that worsen with stress or chewing
Many people are surprised to learn that jaw joint problems don’t always cause jaw pain first; headaches are often the earliest symptom.
Types of Headaches Linked to Jaw Joint Issues
| Headache Type | How TMJ Contributes |
|---|---|
|
Tension Headaches
|
Tight jaw and facial muscles trigger pressure
|
|
Migraine-like Pain
|
Nerve irritation around the jaw and temples
|
|
Sinus-like Headaches
|
Jaw muscle tension mimics sinus pressure
|
|
Morning Headaches
|
Night-time teeth grinding stresses the TMJ |
Why TMJ-Related Headaches Are Often Misdiagnosed
Jaw joint headaches are frequently missed because:
Symptoms overlap with migraines and sinus issues
Jaw pain may not be obvious initially
Many patients consult neurologists or ENT specialists first
Dental causes are not always considered early
As a result, people may rely on painkillers for years without addressing the root cause.
What Causes Jaw Joint Problems?
Jaw joint issues can develop due to several everyday habits and conditions:
Teeth grinding or clenching (often during sleep)
Stress-related jaw tension
Misaligned bite
Missing or uneven teeth
Poor posture (especially long screen time)
Past injury to the jaw or face
The high stress levels, long working hours, and nighttime grinding are major contributors to TMJ problems.
How Are Jaw-Related Headaches Diagnosed?
Diagnosing TMJ disorders requires more than a routine dental check-up.
A proper evaluation may include:
Jaw movement assessment
Muscle tenderness examination
Bite analysis
Imaging (X-rays, CBCT scans if needed)
Treatment Options for Jaw Joint–Related Headaches
The good news is that TMJ-related headaches are treatable.
Common Treatment Approaches
Custom-made night guards or splints
Bite correction if needed
Jaw muscle relaxation therapy
Lifestyle and posture guidance
Stress management techniques
Most patients experience significant headache relief within weeks, once the jaw strain is reduced.
Simple Habits That Can Reduce Jaw-Related Headaches
You can support treatment by:
Avoiding chewing gum
Reducing hard or chewy foods
Practising jaw relaxation exercises
Maintaining correct posture
Managing stress levels
Avoiding clenching during the day
Small changes can make a big difference over time.
When Should You See a Dentist for Headaches?
You should consider a dental evaluation if:
Headaches are frequent or recurring
Painkillers give only temporary relief
You notice jaw clicking or stiffness
Headaches worsen in the morning
Facial or jaw pain accompanies headaches
Ignoring these signs may allow the problem to worsen over time.
Final Thoughts
Not all headaches and migraines start in the head. In many cases, the jaw joint plays a hidden role in triggering ongoing pain. Identifying and treating jaw-related issues can significantly reduce headache frequency and improve daily comfort.
If your headaches keep returning despite medication, it may be time to look beyond the usual causes and consider a jaw joint evaluation. At Summit Dental Clinic, we help identify dental causes of chronic pain and guide patients toward long-term relief.
