A 25-year study of 6,000+ adults found that regular flossing was linked to a lower risk of ischemic stroke and atrial fibrillation (AFib).
Researchers believe inflammation from poor oral health may play an important role in the mouth–body connection.
Compared to non-flossers, regular flossers showed:
• 22% lower risk of ischemic stroke
• 44% lower risk of cardioembolic stroke
• 12% lower risk of AFib
Another reminder that oral health is deeply connected to systemic health.
