Could a simple piece of dental floss be the key to unlocking a longer, healthier life?
Story Snapshot
- Regular flossing is linked to lower risks of strokes and heart issues.
- A 25-year study connects oral health with cardiovascular and brain health.
- Flossing reduces oral inflammation, potentially preventing serious diseases.
- Findings presented at the American Stroke Association’s 2025 conference.
The Power of Flossing
Recent research presented at the American Stroke Association’s 2025 conference reveals that regular dental flossing might significantly reduce the risk of serious health issues like ischemic strokes, cardioembolic strokes, and atrial fibrillation. This study, drawing from 25 years of data gathered by the Atherosclerosis Risk in Communities (ARIC) study, involved over 6,000 participants. The results suggest a 22% lower risk of ischemic stroke and a striking 44% reduction in cardioembolic stroke risk for those who floss regularly.
Flossing, often seen as a mundane task, might hold the key to reducing oral inflammation and infections linked to cardiovascular and brain health issues. Unlike brushing or regular dental visits, flossing specifically targets the spaces between the teeth where harmful bacteria thrive. This study highlights the importance of maintaining a healthy oral microbiome, which can have significant implications for overall health.

Long-term Evidence and Historical Context
The ARIC study, initiated in 1987, is among the earliest and most comprehensive studies tracking the relationship between oral habits and atherosclerosis risks. Over the decades, researchers have found compelling evidence that poor oral hygiene can lead to an increased risk of various chronic diseases, including cardiovascular disease and diabetes. The latest findings build on this foundation, underscoring the importance of flossing as a preventive measure.
Historically, centenarians have been found to retain more of their natural teeth, a testament to the link between oral health and longevity. This connection, observed over the past 50 years, is gaining renewed attention as researchers continue to explore the intricate relationship between oral hygiene and overall health.
Stakeholders and Their Motivations
The study’s lead researcher, Dr. Souvik Sen, emphasizes the potential of flossing as an accessible and affordable habit for stroke prevention. The American Heart Association and American Stroke Association, which hosted the conference, are keen on integrating oral care into broader health guidelines. These organizations, alongside the ARIC Study Consortium, aim to disseminate the findings to encourage better oral health practices among the general public.
Within the academic community, experts like Professor Judith Jones and Assistant Professor Jonathon Baker provide additional insights into the importance of maintaining oral health for longevity. Their research highlights the potential of flossing to disrupt harmful microbial ecosystems within the mouth, thereby reducing inflammation and disease risk.

Current Developments and Future Implications
The preliminary results of this study, announced in January 2025, have sparked considerable interest. Although the findings have not yet undergone peer review, they offer promising insights into the potential health benefits of regular flossing. These developments could lead to the inclusion of flossing in cardiovascular health guidelines, transforming a simple daily habit into a powerful tool for disease prevention.
In the short term, these findings are expected to boost the adoption of flossing as a preventive measure against stroke and atrial fibrillation. In the long term, they could influence public health policies and guidelines, encouraging more individuals to prioritize their oral health as part of a comprehensive approach to disease prevention.
