There are millions of germs that live in your mouth. If you suffer from gum disease, you have open wounds in your gums that allow these bacteria to enter directly into your blood stream and circulate throughout your body. Some of the bacteria normally found in the mouth enter your bloodstream through infected gums and can relocate to other parts of your body, with the potential of creating disease in organs and systems.
Much research is being done to investigate if a definitive link exists between periodontal disease and other systemic illnesses. For now, many of the results are inconclusive.

Gum disease is the leading cause of tooth loss for the majority of adults in the United States. Losing your teeth however is not the only danger of this disease.
