Flossing May Reduce Risk of Stroke and Irregular Heart Rhythm
New research suggests that flossing regularly may lower the risk of some strokes and a type of irregular heart rhythm that can increase stroke risk.
Study Findings
The study, which will be presented at the American Stroke Association’s International Stroke Conference in Los Angeles, found that people who floss at least once a week had a lower risk for strokes caused by blood clots coming from the heart and for an irregular heart rhythm called atrial fibrillation (AFib) that can lead to a stroke.
The study included 6,278 participants who had answered questions about their home use of dental floss. About 65% of the participants reported flossing at least once a week.
Risk Reduction
Compared to non-flossers, people who floss regularly experienced a:
- 22% lower risk of an ischemic stroke
- 44% lower risk of a cardioembolic stroke
- 12% lower risk of AFib, which developed in 20% of study participants
Link to Oral Health and Inflammation
Dr. Souvik Sen, lead researcher and professor and chair of the neurology department at the University of South Carolina, explained that flossing reduces oral infections and gum disease, which are linked to inflammation. "Inflammation can contribute to the risk for stroke, so it would make sense that if people floss regularly, it might also reduce the risk of stroke and AFib," he said.
Additional Insights from Experts
Dr. Karen Furie, neurologist-in-chief at Brown University Health, noted that flossing helps remove debris from between teeth that brushing alone might miss, which can contribute to systemic inflammation. She was surprised that the study found no association between flossing and thrombotic strokes, which are linked to inflammation and atherosclerosis.
Conclusion
The study suggests that flossing regularly may be an important addition to a healthy lifestyle for reducing the risk of stroke and AFib. While more research is needed to confirm the findings, the study’s results provide a compelling argument for prioritizing oral health in overall health maintenance.
Frequently Asked Questions
Q: Can flossing really reduce the risk of stroke and AFib?
A: Yes, the study suggests that flossing regularly may lower the risk of certain types of stroke and AFib.
Q: How does flossing reduce the risk of stroke and AFib?
A: Flossing reduces oral infections and gum disease, which are linked to inflammation. Inflammation can contribute to the risk for stroke, so flossing may help reduce this risk.
Q: Is flossing the only way to reduce the risk of stroke and AFib?
A: No, managing blood pressure and cholesterol, maintaining a healthy weight, staying physically active, eating a healthy diet, and getting enough sleep are all important steps to help prevent strokes. Flossing is one additional way to reduce the risk.
