Chest Pain and Jaw Pain: Common Causes and Mechanisms
Cardiac Causes: Myocardial Ischemia, Angina, and Heart Attack
Chest pain and jaw pain are often linked to heart problems, especially myocardial ischemia, angina, and heart attacks. When the heart does not get enough oxygen, it can cause pain in the chest that may radiate to the jaw, left shoulder, neck, or upper back. This is because the nerves that carry pain signals from the heart can also send signals to these other areas, a phenomenon known as referred pain. This type of pain is often described as crushing, squeezing, or a sensation of pressure in the chest, and it can be triggered by physical activity, emotional stress, or even eating a large meal. Recognizing these symptoms is important because they can signal a heart attack, which requires immediate medical attention 13457.
Neuroanatomical Pathways: Why Cardiac Pain Radiates to the Jaw
The reason heart pain can be felt in the jaw is due to the way nerves from the heart and face converge in the brainstem, specifically at the trigeminal nucleus. This overlap allows pain from the heart to be "felt" in the jaw, face, or even teeth, making it sometimes hard to distinguish from dental problems. Both typical and atypical cardiac pain can be referred to the jaw, with atypical pain more common in women and sometimes felt in the back or neck as well 17.
Other Chest and Throat Disorders Causing Jaw Pain
Not all chest and jaw pain is due to heart problems. Other organs in the chest and throat can also cause pain that is felt in the jaw or face. These include the aorta (such as in aortic dissection), esophagus (like acid reflux), stomach, lungs, mediastinum, thyroid gland, and carotid arteries. Conditions such as aortic dissection, mediastinal tumors, subacute thyroiditis, and gastroesophageal reflux disease can all refer pain to the orofacial region. This overlap can make it difficult to tell the difference between dental pain and pain from a serious internal problem 26.
Importance of Accurate Diagnosis
Because many serious conditions can cause chest and jaw pain, it is important for healthcare providers to rule out life-threatening causes like heart attack and aortic dissection before considering less dangerous explanations. Misdiagnosis can lead to delays in treatment and unnecessary procedures. Dentists and doctors should work together to ensure that patients with unexplained jaw pain are evaluated for possible heart or other visceral problems, especially if they also have chest pain 246.
Public Awareness and Response
Most people recognize chest pain and jaw pain as warning signs of a heart attack, but many still lack confidence in identifying these symptoms and seeking help quickly. Health education is important to ensure that people know when to seek emergency care, as prompt treatment can save lives .
Conclusion
Chest pain and jaw pain are most commonly associated with heart problems like angina and heart attacks, but can also be caused by other serious conditions involving the chest and throat. The pain is often referred due to shared nerve pathways. Accurate and prompt diagnosis is critical, and both the public and healthcare providers should be aware of the wide range of possible causes to ensure timely and appropriate care 1234567.
