What does jaw pain feel like during a heart attack?

Deep throbbing: Most commonly reported is a deep, throbbing pain which seems to be coming from a lower molar and radiating to ear or down the arm. Mimics a tooth that is abscessed and needs a root canal.

An aching: Pretty much an aching of the jaw (more commonly the left jaw joint,) and it doesn't really change with chewing and functions. Is one of the signs of a heart attack that are taught in CPR courses.

Left sided: The symtpoms are left sided. There are enough symptomatic variables that, at your age, any unexplained left sided jaw pain should be explore with your MD.
