Yes. Recent medical research has caused many doctors to reach a startling conclusion: gum disease, stroke, and heart disease are linked. Since heart disease is usually fatal, it is clear that gum disease is a serious matter. The American Dental Association estimates that 8 out of 10 Americans have periodontal (gum) disease. If this were any other affliction, such as AIDS or tuberculosis, it would be considered an epidemic! Most dentists think it is just that.
