Flossing is important for dental health, but did you know it can also prevent stroke? A new study suggests that flossing at least once a week may lower your risk of stroke caused by a blood clot. 

The study, presented at a meeting of the American Stroke Association, found that flossing can lower the risk of clot-caused strokes by 22 percent and lower the risk of strokes caused by blood clots traveling from the heart by 44 percent. In addition, flossing can reduce the risk of atrial fibrillation by 12 percent. 

Why Floss?  

There are several reasons why adding flossing to regular brushing and dental visits may help lower the risk of stroke.

• It helps clear debris from between teeth that brushing might miss. Stuck food can cause inflammation in the gums that can lead to a systemic inflammatory state if not removed. 
• It reduces the occurrence of oral infections and gum disease, which are also linked to inflammation. 
• It clears plaque from the teeth, preventing inflammation in the arteries that supply blood to your brain. 

This study points out that flossing may indicate an overall healthy lifestyle. Those who floss are more likely the same people who follow the recommendations of their dentists and doctors and are attentive to their health needs. People who don’t floss might be less likely to follow healthcare recommendations or could have other underlying medical factors. 

Flossing is just one factor of a healthy lifestyle. To prevent stroke, healthcare professionals also recommend:

• Managing blood pressure and cholesterol 
• Maintaining a healthy weight 
• Staying physically active 
• Eating a healthy diet 
• Getting enough sleep consistently
