Physicians have found a strong link between oral health and heart disease. The plaque on your teeth is a home for bacteria, which can enter your bloodstream. These can help form clots in your coronary artery and intern cause heart attacks. The bacteria in your mouth could also weaken your immune system and cause chronic inflammation throughout the body including the coronary arteries. This inflammation could then lead to hardening of the arteries. To help reduce your risks, regular dental cleanings and checkups are recommended. Chronic oral infection has also been linked to low birth weight and premature deliveries.
