How Flossing Your Teeth Could Help Prevent Stroke and Heart Arrhythmia

Marielaina Perrone, DDS, shares the surprising connection between oral hygiene and cardiovascular health.

When most people think about flossing, they think of preventing cavities or gum disease. But what if this simple daily habit could also lower your risk of stroke or heart conditions like atrial fibrillation?

At **Marielaina Perrone, DDS**, we are committed to empowering our patients with knowledge that not only brightens their smile but also extends their life. Recent research is illuminating the profound connection between oral health and overall wellness, particularly heart health, giving you more control over your health journey.

🧬 The Hidden Link Between Flossing and Cardiovascular Health

Groundbreaking findings presented at the American Stroke Association’s International Stroke Conference 2025 have revealed a compelling association between regular flossing and reduced risk of serious cardiovascular events.

The study, led by Dr. Souvik Sen, Chair of Neurology at Prisma Health Richland Hospital and the University of South Carolina School of Medicine, analyzed data from over 6,000 adults as part of the Atherosclerosis Risk in Communities (ARIC) study. This long-term study, which began in 1987, aims to investigate the causes of atherosclerosis and its clinical outcomes.

Key findings among participants who flossed at least once a week:

• 22% lower risk of ischemic stroke
• 44% lower risk of cardioembolic stroke
• 12% lower risk of atrial fibrillation (AFib)

These results held strong even after accounting for other oral health habits, such as brushing frequency and dental checkups. The implications? Flossing may be more than just a dental hygiene recommendation — it could be a lifesaving routine.

🦠 How Oral Health Affects Heart Health

So, what’s the connection?

The mouth is a gateway to systemic inflammation. When flossing is neglected, bacteria can build up along the gum line, potentially leading to gum infections like periodontitis. These bacteria and inflammatory markers can then enter the bloodstream, contributing to conditions like atherosclerosis — the hardening of arteries — which is a major risk factor for strokes and heart attacks.

By flossing daily, you remove plaque and debris from areas your toothbrush can’t reach, reducing harmful bacteria and lowering systemic inflammation that may impact the heart and brain.
