Can Jaw Pain Be a Sign of a Heart Attack?

Jaw pain is a recognized symptom of a heart attack, and in rare cases it can be the only symptom a person feels. The pain originates not from the jaw itself but from the heart, which shares nerve pathways with the face and teeth. Because most people expect a heart attack to announce itself with crushing chest pain, jaw discomfort that comes on suddenly or during physical activity is easy to dismiss or misattribute to a dental problem.

Why the Heart Sends Pain to the Jaw

When blood flow to the heart muscle is blocked or severely reduced, the starved tissue releases a mix of chemicals, including adenosine and bradykinin, that fire up the heart’s pain-sensing nerve fibers.¹ Those signals travel along sympathetic and vagal nerve pathways toward the brain. Under normal circumstances you would feel this as chest pain. But the brain’s wiring is not always neat: incoming heart signals and incoming face signals converge at the trigeminal nucleus in the brainstem, the same relay station that processes sensation from your jaw, teeth, and temples.² When both sets of signals pile into the same junction, the brain can misread the source and project the pain onto the jaw instead of, or in addition to, the chest.

This phenomenon is called referred pain, and it is not unique to the heart. A gallbladder attack, for instance, can produce shoulder-blade pain through a similar nerve-convergence mechanism. The heart’s version happens to share wiring with the face, which is why jaw, throat, and even tooth pain can all crop up during cardiac events.

How Common Is Jaw Pain During a Heart Attack

A prospective multicenter study that enrolled patients with confirmed cardiac ischemia found that about 32 percent reported craniofacial pain alongside discomfort in other regions. In a smaller subset, roughly 6 percent, the face or jaw was the only location where they felt any pain at all. Three of those patients were having a full-blown heart attack with no chest symptoms whatsoever. The most commonly reported craniofacial locations were the throat, the left side of the lower jaw, the right side of the lower jaw, the area around the ear and temporomandibular joint, and the teeth.³

Six percent may sound small, but it is large enough to matter clinically. A systematic review that tried to answer whether dental or jaw pain could be the sole presenting symptom of a heart attack concluded that it can, but also cautioned that the evidence base is thin. Most of the studies that describe this scenario are case reports rather than large trials, so the exact frequency is hard to pin down with confidence.⁴ What researchers can say is that it happens, and that dismissing unexplained jaw pain without considering a cardiac cause is a real diagnostic blind spot.

Women Are More Likely to Have This Symptom

One of the clearest patterns in the research is that women experiencing a heart attack report jaw and neck pain more often than men do. A large population-based study found that men were about half as likely as women to report jaw pain during an acute heart attack, even after accounting for age, medical history, and the severity of the event.⁵ A review of symptom differences across multiple types of acute coronary events confirmed the pattern: women consistently reported more jaw, back, and neck pain, along with nausea, shortness of breath, and palpitations.⁶

A study focused specifically on throat and jaw discomfort during confirmed ischemia found that women were nearly three times more likely to report it than men were.⁷ The same study found no sex difference in rates of chest pain itself, which undercuts the common belief that women “just don’t get chest pain.” They do. But they are also significantly more likely to get jaw and throat pain alongside it or, in some cases, instead of it. The prospective multicenter study mentioned earlier likewise found that craniofacial pain was disproportionately common in women.³

This matters because women already face longer delays in seeking treatment and in receiving a correct diagnosis. If the symptom profile that prompts people to call for help is built around the classic image of a man clutching his chest, someone whose dominant symptom is jaw tightness may not recognize the urgency.

How Cardiac Jaw Pain Differs from a Toothache

Distinguishing heart-related jaw pain from a dental problem is not always straightforward, but there are clues. A review of case reports and clinical cases found that ordinary toothache tends to be sharp and pulsating, while jaw pain from a cardiac event is more often described as oppressive, burning, or a deep pressure. Toothache also tends to be more intense on a subjective scale, while cardiac jaw pain can be a duller, more diffuse ache that is harder to localize to one specific tooth.⁸

Beyond the quality of pain, the biggest clue is what triggers and relieves it. One published case described a patient whose jaw and face pain consistently appeared during ordinary daily activities and went away with rest. An oral exam revealed nothing wrong with the teeth, gums, or jawbone, and imaging of the temporomandibular joint was clean. Because the pain was provoked by physical activity, the patient was eventually referred to a cardiologist, who diagnosed coronary artery disease. The pain turned out to be angina.⁹

That activity-rest pattern is one of the most helpful red flags. Dental pain usually responds to chewing, hot or cold food, or pressing on a specific tooth. It does not usually flare up when you climb stairs or walk briskly and then ease when you sit down. If jaw pain consistently tracks with physical exertion rather than with eating or biting, that should raise suspicion. Other warning signs include jaw pain that spreads to the throat, left arm, or back; jaw pain accompanied by sweating, nausea, or lightheadedness; and jaw pain that comes on at rest but alongside those other symptoms.

Misdiagnosis and Unnecessary Dental Work

When heart-related jaw pain is mistaken for a dental problem, the consequences go beyond a delay in cardiac treatment. Patients have undergone tooth extractions and been treated for temporomandibular disorders before anyone realized the pain was cardiac in origin.⁸ The dental work does not relieve the pain, of course, because the source was never in the mouth. Meanwhile, the underlying heart disease goes untreated.

The problem runs in both directions. Some cardiac chest-pain presentations can mimic gastroesophageal reflux, esophageal spasm, or even lung conditions, and multiple visceral disorders of the chest and throat can refer pain to the face in ways that look a lot like dental disease on the basis of symptoms alone.⁴ Dentists and emergency physicians alike have to keep cardiac causes on the list when orofacial pain does not line up with any clear dental pathology, especially in patients with cardiovascular risk factors.

Atypical Symptoms and Why They Are Dangerous

Jaw pain during a heart attack belongs to a broader category of “atypical” presentations, which also includes shortness of breath as the main complaint, nausea and vomiting without chest pain, fainting, or simple fatigue. A study of more than 20,000 patients with acute coronary syndromes found that roughly 8 percent presented without any chest pain at all. Nearly a quarter of those patients were not initially recognized as having a cardiac event. They were less likely to receive the right medications, and their in-hospital death rate was about three times higher than that of patients who showed up with classic chest pain.¹⁰

Part of the problem is the cultural expectation of what a heart attack looks like. Focus-group research across the United States found that both patients and bystanders expected heart attacks to arrive as sudden, dramatic, crushing chest pain, the kind of scene you see in movies. When symptoms were more ambiguous, like gradual jaw tightness or mounting nausea, people waited to see if it would pass rather than calling for help.¹¹ That delay can be the difference between a treatable blockage and permanent heart damage, or worse.

When to Treat Jaw Pain as an Emergency

Not every episode of jaw pain warrants a trip to the emergency room. If you have a clearly identifiable dental issue, like a cracked tooth, a cavity, or swollen gums around a specific tooth, the cause is almost certainly local. If your jaw clicks or aches after clenching or grinding, that points toward a temporomandibular joint problem. Stress-related jaw tension is extremely common and is not cardiac.

The situations that should prompt urgent evaluation share a few features:

Exertion link: The pain appears or worsens with physical activity and fades with rest.
Accompanying symptoms: You also feel chest tightness, pressure, or heaviness; shortness of breath; sweating without obvious cause; nausea; lightheadedness; or pain radiating into your arm, neck, or back.
No dental explanation: There is no obvious tooth or gum problem, the pain is hard to pinpoint to one spot, and it feels more like pressure or burning than a sharp ache.
Risk factors: You have a history of heart disease, high blood pressure, diabetes, high cholesterol, or smoking, or a strong family history of early heart disease.

If several of those factors line up, treat it as a possible cardiac event. Call emergency services rather than driving yourself, and do not wait to see whether the pain resolves on its own. Time matters: every minute of blocked blood flow causes more heart-muscle damage.

Diabetes and Symptom Presentation

People with diabetes sometimes experience heart attacks with subtly different symptom profiles than people without diabetes. Research comparing the two groups found that while the overall symptom patterns were broadly similar, patients with diabetes were somewhat more likely to present with shortness of breath, and they rated their symptoms as more severe overall. In patients with diabetes, neck and throat pain and arm or shoulder pain showed borderline significance in predicting coronary heart disease, while the classic combination of chest symptoms and sweating was a stronger predictor in people without diabetes.¹ This suggests that diabetes can blur the usual symptom markers, making atypical signs like jaw or neck discomfort slightly more diagnostically useful in that population.

Diabetes also causes nerve damage over time, which can dull pain perception generally. Some people with longstanding diabetes experience what doctors call “silent” ischemia, where blood flow to the heart is compromised but the usual alarm signals are muted. For someone in that situation, any new or unusual pain above the shoulders, including jaw pain, deserves a closer look.

Vasospastic Angina and an Unusual Trigger

Not all cardiac jaw pain comes from a blocked artery. Vasospastic angina occurs when a coronary artery temporarily spasms shut, cutting off blood flow briefly before relaxing again. It can produce the same referred pain patterns as a classic heart attack, including pain in the jaw, teeth, arms, and shoulders. A published case described a patient who experienced bilateral toothache after drinking alcohol, with no other symptoms. The tooth pain turned out to be triggered by alcohol-induced coronary artery spasm.¹² This is rare, but it illustrates that cardiac jaw pain does not always fit the exertion-and-rest pattern typically associated with coronary artery blockages.

Stress, TMD, and Overlapping Symptoms

One reason cardiac jaw pain is easy to miss is that so many non-cardiac conditions produce jaw pain too. Temporomandibular disorders are the most common, and they have a well-documented relationship with psychological stress. Chronic stress activates the body’s hormonal stress response, leading to sustained jaw-muscle tension, changes in pain sensitivity, and in some people, a lowered pain threshold that makes the jaw region chronically sore.¹³ That means a large number of people walk around with some degree of jaw discomfort on any given day, making it harder to notice when a new type of jaw pain appears.

The key distinction is not just the quality of the pain but its behavior over time. TMD pain tends to be chronic or recurring, is often worse with jaw movement like chewing or yawning, and responds to treatments like a mouth guard, muscle relaxation, or anti-inflammatory medication. Cardiac jaw pain is more likely to appear suddenly, correlate with exertion or emotional stress rather than jaw use, and come with other symptoms that do not belong in a dental picture. If you have a known history of TMD and your jaw pain suddenly changes character, worsens without an obvious jaw-related trigger, or shows up with sweating or breathlessness, do not assume it is just your usual problem acting up.

Public Awareness Campaigns and the Knowledge Gap

Health organizations in several countries have run public campaigns specifically aimed at broadening people’s understanding of heart attack symptoms beyond chest pain. An evaluation of Australia’s Heart Foundation warning-signs campaign found that patients who were aware of the campaign were significantly more likely to seek help within an hour of symptom onset and to arrive at the hospital within two hours.¹⁴ A separate study looking at the same country’s campaign found no significant difference in the overall median time to hospital between people who had seen the advertisements and those who had not, suggesting that awareness alone does not always translate into faster action.¹⁵

That mixed result is telling. Knowing that jaw pain can be a heart attack symptom is useful, but it has to compete with deeply ingrained expectations about what a real heart emergency feels like. Most people who develop jaw pain will think of a dental problem first, and most of the time they will be right. The challenge is building enough awareness that the small fraction of cases with a cardiac origin gets flagged before critical time is lost.
