No proof that gum disease causes heart disease or stroke (USA)

Despite popular belief, gum disease hasn't been proven to cause atherosclerotic heart disease or stroke, and treating gum disease hasn't been proven to prevent heart disease or stroke, according to a new scientific statement published in Circulation, an American Heart Association journal. Keeping teeth and gums healthy is important for your overall health. However, an American Heart Association expert committee - made up of cardiologists, dentists and infectious diseases specialists - found no conclusive scientific evidence that gum disease, also known as periodontal disease, causes or increases the rates of cardiovascular diseases. Current data don't indicate whether regular brushing and flossing or treatment of gum disease can cut the incidence of atherosclerosis, the narrowing of the arteries that can cause heart attacks and strokes. Observational studies have noted associations between gum disease and cardiovascular disease, but the 500 journal articles and studies reviewed by the committee didn't confirm a causative link
