Angina may cause toothache, but it is relatively rare. Angina pectoris is a sharp temporary ischemia and hypoxia of the myocardium due to insufficient blood supply from the coronary arteries, and is mainly characterized by pain in the precordial area and behind the sternum. The pain may radiate to the sides, neck, teeth, shoulders and jaw. Angina-induced toothache is usually accompanied by angina symptoms, is paroxysmal, and each attack lasts about 10 minutes. And the sudden appearance lasts for 10-30 minutes and can disappear on its own. In addition, there is no pain when the tooth is percussed, and there is no problem with the tooth itself. When a toothache occurs, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
