For many, migraines are a fact of life, an infrequent but not uncommon occurrence of pain and sensitivity that can occur as a result of a number of different triggers. Others live with migraines on a daily basis and are unsure of how to combat them effectively. Today, we will examine what migraines are, how they differ from headaches, and what the most effective treatment methods are.
The Short Answer
Temporomandibular disorder (TMD) can set off migraine attacks, raise how often they arrive, and produce a separate jaw-related headache that closely resembles migraine. Population research places migraine roughly two to six times more often in people with painful TMD. Settling the jaw lowers headache frequency for a good share of patients, though the degree of change varies from person to person.
Can TMJ Disorder Cause Migraines and Headaches?
Yes, and the route it takes matters, because it points to the treatment that will help you. Migraine is classified as a primary headache, which means the mechanism sits in the nervous system instead of in a joint. Your jaw plays three separate roles alongside that mechanism, and telling them apart is where relief starts:
- As a trigger. Sustained strain in the chewing muscles sends pain traffic into the same nerve pathway migraine travels along, which can tip an attack into motion.
- As an amplifier. Long-running jaw pain lowers the threshold at which your nervous system fires, so attacks arrive more often and hold on longer.
- As a lookalike. TMD generates a headache of its own, catalogued by the International Headache Society as 11.7 Headache attributed to temporomandibular disorder. It lands in the temples and in front of the ears, and it is frequently filed under the wrong label for years.
Most people who come to us with this question turn out to have a blend of all three running at once. That blend is treatable, and identifying which part carries the most weight is the work of a proper assessment.
I have lost count of the number of patients who sat down in my chair having spent five or six years cycling through migraine medication, sinus treatment, and vision testing, with nobody once pressing on the muscle in front of their ear. When I do press on it, their eyes widen, because I have reproduced the headache they came in with. That moment is often the first time anyone has connected the two things for them.
What is a Migraine?
A migraine is a variation of a headache that delivers more intense pain and exhaustion. Symptoms are generally more severe than what people experience with an ordinary headache. The occurrence of a migraine can be tied to any number of factors, including stress overload, illness, disrupted sleep, and exposure to harsh lighting for prolonged periods.
The Difference Between TMJ Headaches and TMJ-Related Migraines
Migraines are often more debilitating than ordinary headaches, becoming less of an inconvenience and more of a threat to your wellbeing.
Frequently unilateral in nature, meaning they occur on one side, migraines deliver less coverage yet more intense pain than tension headaches, which tend to be bilateral. Migraines are usually accompanied by bodily reactions such as nausea, vomiting, and light and sound sensitivity.
Treatment for basic migraines usually entails resting in a quiet, dimly lit area. Left untreated, an attack runs anywhere from 4 to 72 hours.
On occasion, an individual with an impending migraine may experience an anomaly known as an aura, where visual disturbances such as flashes of light or blind spots build over 5 to 60 minutes as a warning sign of sorts.
Tension headaches occupy the middle ground, and they are the type most often confused with jaw-related pain. Our breakdown of how TMJ produces headaches sits alongside this article and goes deeper on that comparison.
How Jaw Pain Reaches the Rest of Your Head
Three mechanisms carry pain from a small joint in front of your ear into your temple, your forehead, and behind your eye.
Shared wiring
The trigeminal nerve supplies sensation to your jaw, your temples, your forehead, and the lining surrounding your brain. Signals from the chewing muscles and signals involved in migraine both converge on the same relay point in the brainstem. When that relay is receiving a steady stream of traffic from an irritated jaw, the system has difficulty telling the two apart, and the migraine pathway becomes easier to switch on.
Referred pain from muscle trigger points
The masseter and temporalis are among the strongest muscles in the body relative to their size. Overworked, they develop tight, tender bands that send pain outward to predictable destinations. A trigger point in the masseter refers pain to the temple, the eyebrow, and the ear. One in the temporalis refers pain across the side of the head and into the upper teeth. Your brain reads the arriving signal as a headache, because that is where the pain is being felt.
A nervous system that stops filtering
Given enough months of repeated input, the pain system adjusts its own settings. Thresholds drop, and stimuli that were previously unremarkable start registering as painful. Researchers call this central sensitisation, and it explains why a person in this state also becomes more reactive to bright light, noise, weather shifts, and stress. This is the piece that responds most clearly once the source of the input is quieted down.
How to Tell if a Migraine is Caused by TMJ
Migraine pain can be the direct result of many different triggers, including genetics, stress, dehydration, hormonal shifts, and light sensitivity. TMD belongs on that list too.
If your temporomandibular joints or jaw hurt any time you experience a migraine, that timing is a strong signal they are acting as a trigger.
Three checks you can run at home
- The pressure test. Place two fingers on the muscle in front of your ear and bite down gently. You will feel the muscle bulge. Release, then press firmly on that spot for about five seconds. Repeat at your temple. Reproducing your familiar head pain, or setting off a wave of it, points toward muscle involvement.
- The function test. Track your pain against jaw activity for a week. Long phone calls, chewy meals, dental appointments, and gum all load the same muscles. Pain that climbs during those hours and eases on quiet days behaves like a jaw problem.
- The morning test. Note how you feel in the first thirty minutes after waking. Head pain that is present on waking, alongside a tight or tired jaw, suggests something happened overnight. Nocturnal clenching is the usual explanation, and our article on sleep bruxism and what it does to your muscles explains why so few people know they do it.
Two or three positives across those checks make a jaw assessment worthwhile. One positive is still useful information to bring with you.
Treatment Options for TMJ-Related Migraine Headaches
At the Ottawa TMJ & Sleep Apnea Clinic, we treat TMD-associated migraines by lowering the load on the joint and the muscles feeding it, then reassessing what remains. Here is what that involves and what the evidence supports.
Custom oral appliance therapy
A specialised, custom-fitted appliance holds the jaw in a position that reduces tension in the joints and muscles that contribute to migraines. It is worn during sleep, when clenching does most of its damage, and it is shaped from a scan of your own bite.
Therapeutic Botox
Botulinum toxin injections settle the involuntary contractions in the masseter, temporalis, and related muscles, which lowers the mechanical load reaching the jaw joint and the nerve. It has been approved as a preventive treatment for chronic migraine since 2010, where chronic migraine means 15 or more headache days per month. It is not indicated for occasional attacks.
Most patients notice a change 10 to 14 days after a first session, with treatment repeated on a 12-week cycle and results tending to improve across cycles. Our page on therapeutic Botox for headache and muscle pain covers the protocol, and an earlier post on Botox as a pain reliever explains the mechanism.
Jaw physiotherapy and daily exercises
Targeted jaw movement restores range of motion, releases jaw muscle guarding, and retrains how the joint tracks. It is slow work that compounds, and it costs nothing beyond a few minutes a day. Six routines you can start at home are set out in our guide to TMJ pain relief exercises.
Daytime habit work
Clenching during concentration is close to universal among the patients we see, and it is invisible to the person doing it. A simple resting position helps: lips together, teeth apart, tongue resting behind the upper front teeth. Setting a recurring phone reminder for the first two weeks builds the awareness.
When to Book an Assessment for Treating TMJ Disorder and Migraines?
An occasional tension headache after a hard week is part of ordinary life. A pattern deserves attention when it looks like this:
- Headaches arrive several times a month and have persisted beyond three months.
- Jaw stiffness or soreness is present on most mornings.
- You grind or clench, or a partner has told you that you do.
- Medication reduces the severity of attacks without changing how often they arrive.
- Ear fullness, ringing, or dizziness accompanies the head pain with no ear infection present.
An assessment covers your headache history, a hands-on examination of the joint and chewing muscles, bite evaluation, and imaging where the picture calls for it.
You will leave knowing which mechanism is driving your pain and what the options are. Referrals are welcome at our clinic, though none is required to book. Browse the full range of services offered at the clinic or read more about TMJ headache and migraine treatment in Ottawa.
Questions Patients Ask
Can TMJ trigger migraines?
Yes. TMD can set off migraine attacks, raise how often they arrive, and create a separate jaw-related headache that resembles migraine. A 2020 national cohort study found people with TMD carried roughly twice the risk of developing migraine compared with matched controls. Treating the jaw reduces headache frequency for many patients.
What does a TMJ migraine feel like?
Pain settles in the temples, behind the eyes, or in front of the ears, often on one side. It usually arrives with jaw soreness, clicking, ear fullness, or morning stiffness, and it grows heavier with chewing, yawning, or long conversations.
Will treating my jaw stop my migraines?
For some people, headache frequency drops considerably once jaw strain settles. For others, jaw treatment removes one contributor while the underlying migraine pattern continues and benefits from neurological care too. An assessment identifies which picture applies before TMJ disorder treatment plan begins.
How soon does TMJ treatment reduce migraine related pain?
Many patients notice easier mornings within two to three weeks of starting appliance therapy. Therapeutic Botox typically shows an effect 10 to 14 days after a first session, improving across subsequent 12-week cycles. Longstanding patterns take longer to shift than recent ones.
