Periodontal Disease and Heart Health
Brushing and flossing may actually save your life.

So what might hardening of the arteries have to do with gingivitis, that
minor villain of toothpaste and mouthwash commercials?
No one is sure yet. Experts know that bacteria from the mouth can enter the
bloodstream through the gums. These same bacteria have been found clumped in
artery plaques. So one theory is that these bacteria stick to the fatty plaques
in the bloodstream, directly contributing to blockages.
Other possibilities lie in the body's own defense mechanisms against
bacteria. One of the body's natural responses to infection is inflammation
(swelling). It's possible that as these oral bacteria travel through your body,
they trigger a similar response, causing the blood cells to swell. This
swelling could then narrow an artery and increase the risk of clots.
That inflammation could be the root of the problem adds to data researchers
are gathering that suggest more and more diseases, including periodontal
disease, heart disease, and arthritis, are partially caused by the body's own
Could Periodontal Disease Cause Heart Attacks?
So could periodontal disease, gingivitis, or another dental disorder,
pericoronitis (when gum tissue around the molars becomes swollen and infected)
cause heart attacks and strokes? It's far too early to say.
"There's no question that there appears to be a connection," says
Gordon Douglass, DDS, past president of the American Academy of Periodontology.
"But the exact relationship between cardiovascular disease and periodontal
disease isn't clear."
"It's like the chicken and the egg," says Desvarieux. "In our
study, we know that people who had higher levels of the bacteria had more
arteriosclerosis, or atherosclerosis. But we can't say whether one caused the
other." The only way to know, he says, is to follow up the people in his
study to see how they fare in the long term.
But even if periodontal disease isn't actually causing heart disease, the
connection could still be important. For instance, periodontal disease might be
an early sign of cardiovascular problems. Heart disease can be hard to catch
early, because many of the conditions that precede it have no symptoms. You
won't ever feel your arteries hardening or your cholesterol rising. But you
might notice bleeding or painful gums.
If further studies bear out the connection between periodontal disease and
heart disease, the next step would be to try treatment, Desvarieux says. Might
taking antibiotics not only help heal oral infections but, as a result, also
lower your risk of heart disease? No one's sure, but it's possible.
It's still too early for official preventive steps, since researchers don't
know exactly how heart disease and periodontal disease are connected.
"Obviously, people worried about heart disease need to pay attention to
the established risk factors," Desvarieux tells WebMD. "I
wouldn't want people to think that if they just started to brush their teeth
more, they could go back to smoking or ignore their diabetes."
