Regular brushing of teeth, which prevents periodontal
disease, may lower the risk of suffering a stroke or a heart attack, reports Mexico City’s Milenio
newspaper. Researchers from the University
of Minnesota found that
people with high levels of bacteria that cause periodontal disease also had a
narrower carotid artery. 
One possible explanation is that “the microorganisms
that cause periodontal disease emigrate and travel throughout the bloodstream,
which stimulates the immune system and provokes inflammation,” says the paper.
In turn, that inflammation increases the buildup of fatty deposits in the
arteries or contributes to the formation of blood clots that can lead to heart
attacks, researchers theorize. Therefore, “caring for oral health may have a
significant impact on cardiovascular health,” says Milenio.
