Once a week?!?
Imagine the benefits if we go 7 for 7!
A study presented at the American Stroke Association's International Stroke Conference 2025 found that people who flossed at least once a week had:
• 22% lower risk of ischemic stroke
• 44% lower risk of cardioembolic stroke (a stroke caused by a blood clot originating in the heart)
• 12% lower risk of atrial fibrillation (AFib), a common irregular heart rhythm that increases stroke risk.
Interestingly, these associations remained even after accounting for toothbrushing habits and regular dental visits, suggesting that flossing may provide unique oral health benefits beyond brushing alone.
Researchers believe the connection may involve gum inflammation. When plaque and bacteria accumulate between teeth, they can trigger chronic inflammation in the gums. This inflammation may contribute to processes involved in cardiovascular disease and stroke. Flossing helps remove plaque from areas a toothbrush cannot reach, supporting healthier gums and potentially reducing the body's inflammatory burden.
A simple habit that takes less than a minute could have benefits extending far beyond the mouth.
