People who floss their teeth at least once a week are reducing their risk of stroke caused by a blood clot, researchers are scheduled to report Wednesday.

Flossing at least once a week may lower the risk of stroke and atrial fibrillation, according to preliminary results from a new study. Flossing was linked to improved overall health, including lower blood pressure, healthier cholesterol levels, and a reduced risk of diabetes.

Poor oral health could be a potential risk factor for cardiovascular disease. New research shows that good oral health habits, such as flossing, may reduce the risk of stroke and atrial fibrillation (AFib).
