How might problems in my mouth be linked to health problems in other parts?

Bacterial Spread: One theory suggests poor oral hygiene leads to more bacterial growth in the mouth which can enter our bloodstream through the gums. These bacteria can then deposit in blood vessels and cause hardening of the arteries, clots, and damage from our body's own immune response to bacteria in the blood (inflammation, etc.).

Easy: There are many manifestations of systemic disease in the mouth, including autoimmune problems, immune deficiency, vitamin deficiencies and others.
