FALSE. Physicians have long suspected that certain oral bacteria promote heart disease and stroke, possibly by contributing to the systemic inflammation that is related to stiffening of the arteries.

What’s more, preventing and treating periodontal disease hasn’t been proved to reduce the incidence of heart attacks or stroke.
