Weekly Flossing Linked to Lower Stroke and Heart Risks, Study Finds

Research highlights how flossing at least once weekly may reduce stroke risk by up to 44% and lower irregular heartbeat occurrences.

A 25-year study involving over 6,200 participants found that flossing at least once a week is associated with a 22% lower risk of ischemic stroke and a 44% lower risk of cardioembolic stroke.
Flossing was also linked to a 12% lower risk of atrial fibrillation (AFib), a common irregular heartbeat condition that increases stroke risk.
Researchers believe flossing reduces oral infections and inflammation, which are tied to systemic inflammation and artery hardening, key contributors to cardiovascular disease.
The findings suggest that flossing's benefits are independent of other oral hygiene habits, such as brushing teeth or regular dentist visits.
Experts propose that good dental hygiene, including regular flossing, could be incorporated into broader health guidelines like the American Heart Association’s 'Life’s Essential 8' risk factors for stroke and heart health.
