Jaw pain and your heart connect in one way that matters tonight: jaw or tooth pain that comes on with exertion and settles with rest should be treated as a heart symptom until a doctor rules that out, which means calling Triple Zero rather than booking a dentist. The Heart Foundation lists the jaw among the sites of heart attack pain, alongside the chest, arm, shoulder, back and neck, and notes that jaw pain can feel like a toothache. There were 57,100 acute coronary events in Australia in 2023, around 156 every day. A dentist cannot rule out a cardiac cause with an examination or an x-ray.
Key takeaways
- Pain in the jaw or teeth brought on by exertion and relieved by rest is a heart symptom until proven otherwise. Call Triple Zero.
- Cardiac referred pain is usually described as pressure or burning. Toothache is usually throbbing and aching.
- Cardiac pain is often not limited to one tooth. It may sit across the lower jaw, throat or ear, on either side.
- Between 8 and 30 per cent of heart attacks present without chest pain, probably an undercount because people who died before reaching hospital were not included.
- People presenting to emergency departments with atypical symptoms had around three times the risk of death compared with those presenting with chest pain.
- The research on dental pain as the only symptom is weak and mostly case reports. That is a reason to be cautious, not a reason to wait and see.
Call Triple Zero now if any of this is happening
Do not read the rest of this page first. If jaw, tooth, throat or ear pain is happening alongside any of the following, call Triple Zero on 000.
- Pressure, tightness, heaviness or burning in the chest, arm, shoulder, back or neck.
- Pain that started or worsened with physical effort, walking uphill or carrying something, and eased when you stopped.
- Shortness of breath.
- Sweating, especially a cold sweat.
- Nausea or vomiting.
- Dizziness, light-headedness or feeling like you might faint.
- Extreme, unexplained fatigue.
Ambulance officers would far rather attend and find a dental problem than have someone wait. Do not drive yourself, and do not take aspirin or anyone else's medication on the strength of a web page. Call 000 and let them decide.
Why the heart can cause pain in the jaw
The heart has no way of telling the brain exactly where it is. Sensory nerves from the heart, travelling in the vagus nerve and the sympathetic chain, arrive at neurons in the upper spinal cord at levels C1 to C3. Those same neurons receive input from the trigeminal nerve, which supplies the face, jaws and teeth. When two inputs share a destination, the brain can misread the source.
Animal work backs this up. In one study, 89 per cent of C1 and C2 spinal neurons that responded to irritant chemicals placed around the heart were also excited by mechanical stimulation of face and jaw structures, and cutting the vagus nerve abolished the cardiac response. There is human evidence too: implanted vagus nerve stimulators have produced toothache and facial pain in people with no dental symptoms, with pain episodes matching the stimulator's cycle of 30 seconds on every five minutes.
The pattern fits the anatomy too. Orofacial pain during cardiac ischaemia is associated with ischaemia of the inferior wall of the heart, which is where vagal nerve endings are densest.
How often does this actually happen
Kreiner and colleagues studied consecutive patients with confirmed cardiac ischaemia using a structured pain questionnaire, published in the Journal of the American Dental Association in 2007. Craniofacial pain was reported by 38 per cent of them. An Australian replication using the same protocol, published in the Australian Dental Journal in 2012, found 34 per cent. A 2020 review reported orofacial pain in around four in ten patients during myocardial ischaemia, and pain only in the orofacial structures in up to 4 per cent of heart attack patients, more often women than men. A separate paper found craniofacial pain was the sole warning symptom before infarction in 5 per cent of patients.
Here is the part most articles get wrong. Those studies started with people already known to be having a cardiac event and asked what hurt. Nobody has taken a population of people with toothache and measured how many were having a heart attack. So 4 per cent of heart attacks does not become 4 per cent of toothaches. The number does not run in that direction.
What the figures do support is simpler. Facial and jaw pain is a real presentation of cardiac ischaemia, and when a heart attack presents without chest pain the risk of a poor outcome rises. Studies put heart attacks without chest pain at 8 to 30 per cent, likely an undercount because people who died before reaching an emergency department were not counted. An emergency medicine study found patients arriving with atypical symptoms had approximately three times the risk of death of those arriving with chest pain, largely because they were recognised later.
Same jaw, four different causes
| Feature | Toothache | Referred cardiac pain | Sinus | Trigeminal neuralgia |
|---|---|---|---|---|
| How it feels | Throbbing, aching | Pressure, burning, suffocating | Dull, heavy fullness | Electric shock, stabbing |
| Brought on by | Hot, cold, sweet, biting | Physical or emotional exertion | Bending forward, a recent cold | Light touch, shaving, wind |
| Relieved by | Painkillers, avoiding the tooth | Rest | Sitting upright, decongestion | Nothing predictable |
| One tooth or several | Usually one | Not tooth specific. Often the jaw, throat or ear, either side | Several upper back teeth at once | Follows one nerve branch |
| Other symptoms | Swelling, gum tenderness | Breathlessness, sweating, nausea, dizziness, fatigue | Blocked nose, facial fullness | None |
| Anaesthetic effect | Numbing the tooth stops it | Numbing the tooth does not stop it | No change | No reliable change |
| What to do | Book a dentist | Call Triple Zero | See a GP or pharmacist | See a GP for referral |
Use that table to recognise a pattern worth acting on, not to talk yourself out of calling for help. No table replaces an electrocardiogram.
What the pain quality research found
A 2010 study in the Journal of Dental Research compared how patients described cardiac and dental pain. Cardiac craniofacial pain was described as pressure, burning, or both. Dental pain was described as throbbing and aching. A later review added that cardiac pain is aggravated by physical activity and relieved by rest, and dental pain is not.
Two other features stand out. When there was no chest pain at all, the most common sites were the upper throat, the left lower jaw, the left jaw joint and ear, the right lower jaw and the back teeth. The left arm was not top of that list. The pain is also often on both sides or poorly localised, which is unusual for a tooth problem.
Women and atypical presentation
The Heart Foundation notes that women are more likely than men to experience jaw pain as a heart attack warning sign, and the orofacial-only presentation was more common in women in the research above. Around 19,700 Australian women had an acute coronary event in 2021.
Two clarifications matter, because this area attracts myths. Jaw pain is not the most common heart attack symptom in women. Chest discomfort remains the most common presenting symptom in both sexes, and women do get chest pain during heart attacks. The accurate statement is narrower: women are somewhat more likely to present with symptoms other than chest pain, and those presentations are recognised later.
When dental treatment has been done for a heart problem
Two published cases show what happens when the pattern is missed. In a case reported in the Journal of the American Dental Association in 1987, a 71-year-old man with pain in a lower premolar was treated as dental and given root canal treatment. The pain did not resolve. An electrocardiogram then showed myocardial ischaemia, and angiography found a 90 per cent blockage of the left anterior descending coronary artery.
In a second case, a 48-year-old man had four months of severe ear and jaw joint pain with no dental, joint or sinus abnormality on examination. He was referred for cardiac assessment, coronary disease was found, and the pain resolved after heart surgery.
These are individual reports, and nobody knows how often this happens. What they illustrate is a useful clue: pain that does not fit a dental cause, and does not respond to dental treatment, needs a different question asked.
How strong is this evidence, honestly
Weaker than most articles admit. A systematic review in the Journal of Emergency Medicine in 2014 examined 18 studies on dental and facial pain as a cardiac symptom. Sixteen were case reports and only two were prospective cohorts. Nine were rated weak, eight moderate and one strong. The authors concluded that the poor methodological quality prevented a firm conclusion that face, jaw or tooth pain can be the sole symptom of cardiac insufficiency.
The supporting studies are also small, and the same research team appears across most of the publications. Case reports carry heavy publication bias, because dramatic misdiagnoses get written up and ordinary toothaches do not.
None of that changes the advice. Weak evidence about how often something happens is not evidence that it does not happen, and the cost of a wrong assumption is very high in one direction and very low in the other. If the pattern fits, call 000.
What a dentist can and cannot do
A dentist can test whether a tooth is alive, whether it hurts to bite on, and whether an x-ray shows infection at the root. Those tests confirm a dental cause. They cannot exclude a cardiac one.
There is one clue dentists use. If numbing the suspect tooth fails to abolish the pain, it is probably referred from elsewhere. Where cardiac referral is suspected, dentists avoid local anaesthetic containing a vasoconstrictor, because it may worsen a coronary blockage.
How this differs from our other jaw pain articles
This site has several articles about pain that feels dental but is not. Our piece on sinus toothache and referred pain covers the most common of them, where several upper back teeth ache together after a cold. Our guide to trigeminal neuralgia or toothache covers electric-shock pain triggered by light touch, and our article on jaw joint and TMJ pain covers the ache that comes with clicking and clenching. This page is about none of those. It is about pain that is not coming from the head at all.
There is a separate cardiac connection worth not confusing with this one. Our article on gum disease and heart health is about a long-term association between chronic gum inflammation and cardiovascular disease over years. This page is about a symptom happening right now.
Common questions
Can a heart attack feel like a toothache?
Yes. Orofacial pain is reported by around four in ten patients during cardiac ischaemia, and in a small proportion it is the only pain. It usually feels like pressure or burning rather than throbbing, and it tends to come on with exertion. If that fits, call Triple Zero.
Can jaw pain be a sign of a heart problem?
It can. The jaw is on the Heart Foundation's list of heart attack pain sites, along with the chest, arm, shoulder, back and neck. The features that raise concern are exertion bringing it on, rest settling it, and any breathlessness, sweating, nausea or dizziness with it.
What does angina jaw pain feel like?
People describe it as pressure, tightness or burning rather than sharp or throbbing. It is often spread across the lower jaw, throat or ear rather than pinned to one tooth, and it is not made worse by hot, cold or biting. The strongest clue is the link to activity and the settling with rest.
Is jaw pain a heart attack symptom in women?
Yes, and the Heart Foundation notes women are more likely than men to experience it. It is not the most common symptom in women, though. Chest discomfort remains the most common presenting symptom in both sexes. The concern is that other symptoms are recognised later, and delay carries higher risk.
When should I go to hospital for jaw pain?
Immediately, by ambulance, if the pain came on with exertion, eases with rest, feels like pressure or burning, or comes with breathlessness, sweating, nausea, dizziness or chest, arm, neck or back discomfort. Call Triple Zero rather than driving. Jaw pain with facial swelling, fever or trouble swallowing is a different emergency that also needs a hospital.
If a heart cause has been assessed and excluded and the pain turns out to be dental, the team at Lumi Dental sees new patients in Melrose Park. There is a current new patient special on our current deals page, and you can contact the practice during opening hours.
