New research suggests that regular flossing may lower the risk of stroke and atrial fibrillation, potentially by reducing inflammation in the mouth and improving overall cardiovascular health.
Oral hygiene is increasingly recognized as a key factor in preventing cardiovascular disease. According to Dr. Suvik Sen, chair of the Department of Neurology at the University of South Carolina School of Medicine, “Flossing was also associated with improved overall health, including lower blood pressure, healthier cholesterol levels, and a lower likelihood of diabetes.” The study, which included over 6,300 participants, found that regular flossing was linked to a 21% reduction in ischemic stroke, a 44% reduction in cardioembolic stroke, and a 12% decrease in atrial fibrillation risk.
Researchers attribute these benefits to reduced systemic inflammation. Oral bacteria can trigger oxidative stress and vascular damage, contributing to conditions such as atrial fibrosis and impaired heart conduction. Dr. Sen explained,
However, experts caution that the study does not establish a direct cause-and-effect relationship. Dr. Harlan Krumholz of Yale University noted, “People who floss regularly often take better care of their overall health, so it’s hard to say whether flossing plays a key role in stroke prevention.” Still, the American Heart Association supports maintaining good oral hygiene as part of an overall strategy for heart health.
The study highlights the simplicity and accessibility of flossing as a preventive measure. As Dr. Sen concluded,
