It seems odd at first to think that your teeth have anything to do with heart health, but there may be a link between heart disease and periodontal disease, which affects both your gums and your bones supporting the teeth. According to the American Academy of Peridontology, people with periodontal disease are nearly two times as likely to have heart disease, although we're not sure why just yet. One theory suggests that bacteria in your gums can enter the bloodstream and attach itself to fat already in your arteries, while another states that the inflammation caused by periodontal disease makes the arteries swell.
While nobody can definitively say that you will prevent heart disease by taking care of your teeth, early signs of periodontal disease -- including bleeding gums -- are much easier to notice than signs of heart disease. Brushing and flossing your teeth regularly, as well as visiting your dentist at least twice a year, will definitely contribute to your overall health.
