New Research suggests flossing can reduce stroke risk by as much as 20%.
Good oral hygiene isn’t just about keeping a bright smile—it could also protect your brain and heart. New research suggests that flossing your teeth just once a week can lower the risk of stroke by more than 20%, offering a simple and effective way for seniors to safeguard their health.
How Flossing Protects Against Stroke
Plaque and bacteria build up in the mouth over time, leading to inflammation that can spread throughout the body. This inflammation is linked to blood clots, heart disease, and strokes—all of which are major concerns for older adults.
A long-term study presented at the American Stroke Association conference analysed data from over 6,000 adults who were tracked for 25 years. The findings showed:
✔️ 22% lower risk of ischemic stroke (the most common type, caused by a blocked artery in the brain) among those who flossed weekly.
✔️ 44% lower risk of cardioembolic stroke (a type of stroke caused by blood clots from the heart).
An Easy Step Toward Better Health
For those aged 65 and older, stroke prevention is crucial. While regular flossing may seem like a small habit, it can reduce inflammation, improve circulation, and lower stroke risk—all without medication or major lifestyle changes.
Dr. Souvik Sen from the University of South Carolina explains:
💬 “Oral health is linked to inflammation and artery hardening. Flossing may reduce stroke risk by lowering oral infections and inflammation—plus, it’s an easy, affordable habit.”
If you find traditional floss difficult to use, consider floss picks, water flossers, or interdental brushes to keep your gums healthy and your risk lower.
With 100,000 strokes each year in the UK, prevention matters! A simple habit like flossing could help protect your heart & brain—and it’s never too late to start.
