Sometimes, a toothache may be caused by a problem not originating from a tooth or the jaw. Pain around the teeth and the jaws can be symptoms of diseases of the heart (such as angina or heart attack), ears (such as inner or external ear infections), and sinuses (air passages of the cheek bones). For example, the pain of angina (inadequate supply of oxygenated blood to the heart muscle because of narrowing of the arteries to the heart) is usually located in the chest or the arm. However, in some patients with angina, a toothache or jaw pain are the only symptoms of their heart problem. Infections and diseases of the ears and sinuses can also cause pain around the teeth and jaws. Therefore, evaluations by both dentists and doctors are sometimes necessary to diagnose medical illnesses causing toothache.
