Research has shown that gum disease can influence heart disease and other health conditions in negative ways. They suggest that gum disease could even be a more serious factor in heart disease than smoking, cholesterol, hypertension and age. One reason for this is the fact that the bacteria found in diseased gums can come loose and move throughout the body. When this bacteria reaches arteries it can cause arterial plaque to build up and harden which in return adversely affect blood flow.
