For decades, doctors have linked gum disease to heart disease but now an expert panel says there is no proof one causes the other.
For years studies have suggested that bacteria in the mouth can get into the bloodstream and cause heart problems.
But a new statement from the American Heart Association says there is no proof gum disease causes heart disease or stroke..
After reviewing hundreds of studies, researchers also say that treating gum disease, including brushing and flossing, does not reduce the risk of cardiovascular disease.
Experts say the same risk factors can cause both diseases so many people who smoke, have diabetes or high blood pressure can suffer gum and heart problems.
An American Heart Association expert committee made up of cardiologists, dentists and infectious disease specialists published today's statement in the journal circulation.
