(HealthDay News) -- A heart attack occurs when an area of heart muscle dies or is damaged because of a lack of oxygen.
Occasionally heart pain can radiate to the jaw and teeth.
Typically, pain occurs as a tightness or squeezing in the chest or behind the sternum that lasts longer than 20 minutes. But in rare cases the pain can also start in the jaw or teeth, according to the U.S. National Library of Medicine.
If you suspect you might be having a heart attack, seek medical attention immediately.
