Researchers Link Gum Disease to Increased Risk of Stroke, Brain Damage
Researchers link combined gum disease and cavities to an 86% higher stroke risk and brain white matter damage, highlighting oral health's role in stroke prevention.
- A study led by Dr. Souvik Sen found that having both gum disease and cavities is linked to an 86% increased risk of stroke, according to CBS News on October 22, 2025.
- As a possible mechanism, researchers found adults with gum disease showed signs of brain white matter damage, and Sen said `Gum disease is associated with a higher chance of inflammation, and inflammation has been tied to atherosclerosis as well as hardening of the small blood vessels, as we saw in this study` .
- Sen warned that `What the study suggested was that if you have cavities on top of gum disease, it is double trouble. It means your risk of stroke or adverse heart event doubles,` but the researchers caution the work shows association and not causation.
- Taking care of the mouth with preventive oral care is linked to reduced stroke risk, with Dr. Souvik Sen saying risk dropped by as much as 81%.
- With 3.5 billion people worldwide affected by gum disease or cavities, the World Health Organization highlights prevention as key amid more than 795,000 annual U.S. strokes, the American Heart Association reports.
