You may think of flossing as a way to keep your teeth and gums healthy, but new research shows that it may also protect your heart and brain. Recent scientific studies reveal compelling connections between gum health, stroke risk, and chronic migraines.
A major study led by Dr. Souvik Sen at the University of South Carolina found that flossing at least once a week can cut your risk of ischemic stroke by 22% and cardioembolic stroke by 44%. Flossing also lowers the risk of atrial fibrillation, a heart rhythm problem that raises stroke risk. These benefits are similar to those of aspirin but without the side effects of increased bleeding and stomach ulcers. The reason may be that flossing reduces gum disease and oral inflammation, which are linked to heart and blood vessel problems.
Two recent reviews have highlighted that people with gum disease (periodontitis) are more likely to suffer from migraines. One large observational study found that those with periodontitis had a 29% higher risk of migraines, and the worse the gum disease, the higher the risk. A systematic review of eight studies confirmed this link, pointing to inflammatory markers, like CGRP and PTX3, that are elevated in both conditions. Chronic inflammation from gum disease may trigger or worsen migraine attacks.
Flossing is a simple, affordable way to lower your risk of stroke and potentially reduce migraine frequency. By keeping your gums healthy, you’re also helping to protect your heart and brain.
