The link between oral health and stroke risk
Today we mark World Stroke Day, with the theme “Every Minute Counts” emphasising how prevention and early action save lives. Here at Dental Health Foundation Ireland, we want to highlight the important role of oral health in stroke prevention.
Recent research shows that individuals with both gum disease (periodontitis) and untreated decay face up to an 86 % higher risk of stroke compared with those with healthy mouths. Poor oral health allows bacteria and inflammation to enter the bloodstream, which may contribute to damaged blood vessels and increased stroke risk.
What this means for you:
Brush twice daily with fluoride toothpaste, clean between your teeth daily (with floss or interdental brushes).
Visit your dentist regularly for check-ups and cleanings.
Don’t ignore symptoms like bleeding gums, bad breath or tooth pain—they may signal gum disease.
Maintain a healthy lifestyle overall (lower sugar diet, maintain healthy blood pressure, don’t smoke) — supporting both oral and brain health.
By recognising that “the mouth is part of the body”, dental professionals play a key role in reducing stroke risk. Let’s use this World Stroke Day to raise awareness in our practices and with patients: good oral care is not just about your smile—it could also help protect your brain.
