April 18, 2012 (CHICAGO) --Despite popular belief, the health of your teeth and heart may have nothing to do with each other afterall. A new scientific statement from the American Heart Association says there is no convincing evidence linking untreated gum disease to heart disease or stroke. It also says there is no proof that treating gum disease can reduce your risk of heart disease or stroke. An extensive analysis looking at the perceived link has been in the works for three years. Details are in the journal, "Circulation."
