Possible Link Between Oral Health And Heart Health, From The Harvard Heart Letter

The billions of bacteria and
other microscopic critters that live in the mouth unquestionably influence
the health of teeth and gums. But do they also cause problems for the heart
and blood vessels? And can improving oral health prevent cardiovascular
problems?



The notion that problems in the mouth cause diseases elsewhere in the
body makes sense but has been difficult to prove, explains the Harvard
Heart Letter. Scientists are exploring several mechanisms that may connect
the two processes. In people with periodontitis (erosion of tissue and bone
that support the teeth), chewing and toothbrushing release bacteria into
the bloodstream. Several species of bacteria that cause periodontitis have
been found in the atherosclerotic plaque in arteries in the heart and
elsewhere. This plaque can lead to heart attack.



Oral bacteria could also harm blood vessels or cause blood clots by
releasing toxins that resemble proteins found in artery walls or the
bloodstream. The immune system's response to these toxins could harm vessel
walls or make blood clot more easily. It is also possible that inflammation
in the mouth revs up inflammation throughout the body, including in the
arteries, where it can lead to heart attack and stroke.



Although we sill have a lot to learn about whether, and how,
periodontitis and other oral problems are linked to heart disease, the
Harvard Heart Letter notes that it still makes good sense to take care of
your teeth. Brush and floss every day, and see your dentist at least twice
a year for regular cleanings and oral exams. This will pay off for your
oral health and just may benefit your heart as well.
