Flossing’s benefits go beyond gum health, another study shows

Do you floss your teeth? It may help reduce your risk of a stroke, researchers from the University of South Carolina say.

They analyzed data from nearly 6,300 participants in the Atherosclerosis Risk in Communities Study and asked the study group about their flossing habits.

The researchers then followed the participants for 25 years.

What they found: Flossing at least once a week was linked to a 22% lower risk of ischemic stroke and a 44% lower risk of cardioembolic stroke – when blood clots travel from the heart. The participants who flossed regularly also had a 12% lower risk of irregular heartbeat, known as atrial fibrillation.

In a press release, American Academy of Periodontology President Mia Geisinger said poor flossing habits can result in plaque buildup around the teeth and gums, which may lead to inflammation and the growth of bacteria. Inflamed gums can trigger gum disease. Geisinger notes that the study results are consistent with previous research that shows gum disease can increase the risk of cardiovascular disease.

“This ‘one-two punch’ of increased inflammation and bacterially induced damage to blood vessels and their role in heart disease and stroke make establishing and maintaining oral health critical to overall health,” Geisinger said. “Flossing is a simple, low-cost way to take care of your smile, and it may help your heart in addition to your gums.”
