It’s a question we hear often at the clinic: “Could my headaches be coming from my jaw?”

In many cases, the answer is yes, or at least, your jaw may be contributing to your symptoms.

Muscle tension around the temporomandibular joint (TMJ), located just in front of the ear, can easily radiate to the temples, forehead, back of the head, and even the neck. These symptoms can closely resemble migraines or tension-type headaches, making the true source difficult to identify.

In this article, we explain why the TMJ can cause headaches and how physiotherapy can help provide long-term relief for both jaw pain and headaches.

Why can the jaw trigger headaches?

The TMJ is a complex and powerful joint. It’s one of the most frequently used joints in the human body. Every time you talk, eat, yawn, or swallow, it’s activated, more than 2,000 to 3,000 times a day!

Because it relies on several muscles that connect directly to the temples, forehead, and neck, tension in this area can easily translate into headaches.

Here are three well-known mechanisms that explain this connection:

1. Muscle tension

Jaw muscles such as the masseter and temporalis work closely with muscles of the skull and neck. When these muscles become overly tense (due to stress, poor posture, one-sided chewing, jaw clenching habits, or other factors), they can lead to:

  • localized pain in the temples,
  • pressure behind the eyes,
  • a tight, band-like sensation around the head, typical of tension headaches.

2. Bruxism (teeth grinding or clenching): 

Bruxism is very common during periods of stress, emotional strain, or fatigue. It causes the jaw to work much harder than necessary, leading to:

  • prolonged contraction of TMJ muscles,
  • irritation that can radiate to the temples,
  • headaches upon waking or later in the day,
  • jaw fatigue or pain when opening the mouth or chewing.

Bruxism can also increase neck stiffness, further intensifying headaches.

3. TMJ irritation or dysfunction

When the jaw joint doesn’t move smoothly, if it clicks, deviates, locks, or becomes inflamed, it can cause pain that radiates along the trigeminal nerve, a nerve involved in many types of headaches.

TMJ dysfunction may cause: 

  • referred pain in the cheek, temples, or head,
  • burning or tight sensations,
  • headaches that worsen with chewing or mouth opening.

How can you tell if your headaches are coming from your jaw?

Some common warning signs include (but are not limited to): 

  • headaches that start in the temples or near the ears,
  • pain that worsens with talking, yawning or chewing,
  • clicking, locking, or deviation of the jaw,
  • stiffness or pain upon waking in the neck or jaw,
  • tenderness in the cheeks or temples,
  • pain that travels down into the neck.

If these symptoms sound familiar, it’s very possible that your TMJ is involved.

How can physiotherapy help?

Physiotherapy plays an important role in managing TMJ-related headaches.

Our trained professionals can help you:

  • identify the true source of your headaches. Sometimes it can be your jaw or your neck.
  • reduce muscle tension in the TMJ using internal and external manual techniques, based on your needs,
  • improve jaw movement to reduce clicking, prevent locking, and restore smoother motion,
  • strengthen the neck and improve posture,
  • manage stress-related tension through exercises, education, and relaxation strategies.

The goal: treat the root cause of the pain and prevent it from coming back. A thorough assessment can quickly determine whether the TMJ is involved and guide a personalized treatment plan.

Jaw pain and headaches are far more connected than most people realize. With a clear understanding of the underlying causes and the right professional support, it’s possible to achieve lasting relief, for both your jaw and your head.
