A new study suggests that people who regularly floss their teeth may lower their risk of stroke caused by blood clots traveling from the heart. The research, presented at the American Stroke Association’s International Stroke Conference 2025, found that flossing was associated with a 22% lower risk of ischemic stroke and a 44% lower risk of cardioembolic stroke.
Researchers analyzed data from over 6,000 participants who used dental floss regularly. They discovered that flossing not only lowered the risk of stroke but also reduced the incidence of cavities and periodontal disease.
The benefits of regular flossing appear to be independent of tooth brushing and other oral hygiene behaviors. Increasing the frequency of flossing was associated with a greater chance of reducing stroke risk.
According to study lead author Souvik Sen, “Flossing is a healthy habit that is easy to adopt, affordable and accessible everywhere.” The researchers believe that flossing may reduce stroke risk by lowering oral infections and inflammation.
The study’s findings are considered preliminary until published in a peer-reviewed scientific journal. However, they offer more insights into the specific dental health behaviors linked to stroke risks and potential risk reduction.
Flossing has long been recognized as an essential part of good oral hygiene, but this new research highlights its potential role in preventing cardiovascular disease. The American Stroke Association is committed to funding innovative research and promoting public health policies to reduce the burden of stroke.
