Rosie Mestel, L.A. TimesCurrent 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.”
Oh Rosie, oh Rosie... Half-assed knowledge is what produces an article like that.
This is nothing new. At least not here in Europe. The risk though is not in the incidence of atherosclerosis, but endocarditis. Gum disease does cause a relevant bacteriemia (a morbid level of bacteria in your blood ). And that will sooner or later cause your heart valves to be infected. And that's far worse than atherosclerosis.
