Summary: Poor Oral Health and Cardiovascular Risk
Summary: Poor Oral Health and Cardiovascular Risk
Source: October 22, 2025 – Journal of the AAN (American Academy of Neurology)
(21-year follow-up study showing that poor oral health (gum disease + cavities) is strongly associated with higher stroke and heart-attack risk).
Keynotes:
1. Study Overview:
• Data from nearly 6,000 adults (mean age 63) with no prior heart or stroke history were followed for a median of 21 years.
2. Key Findings:
• Individuals with gum disease + cavities had an 86% higher stroke risk.
• Gum disease alone increased stroke risk by 44%.
• Those with both conditions faced a 36% higher risk of any major cardiovascular event (heart attack or stroke).
• These associations persisted after adjusting for confounding factors.
3. Protective Effect of Dental Care:
• Regular dentist visits were linked to an 81% lower risk of having both gum disease and cavities.
4. Interpretation:
• According to lead author Dr. Souvik Sen (University of South Carolina), improving oral hygiene may play a meaningful role in stroke prevention.
• “Taking care of your teeth and gums isn’t just about your smile—it could help protect your brain.”
5. Causality Note:
• The study shows a strong association, not direct causation.
• Further research is needed to clarify biological mechanisms linking oral inflammation to vascular disease.
