11 Sep 2025 : A new study has revealed a strong connection between oral health and heart health, suggesting that poor oral hygiene may significantly increase the risk of heart attacks.
The study, conducted by researchers at the European Society of Cardiology (ESC), analyzed data from over 1.5 million participants across multiple countries, tracking their dental health habits and cardiovascular outcomes over 10 years. Findings show that individuals with gum disease, untreated cavities, or infrequent brushing habits had up to 25% higher risk of heart attacks compared to those who maintained proper oral hygiene.
The Mouth-Heart Connection
Experts explain that the link lies in inflammation. Poor oral hygiene can lead to gum infections (gingivitis) and periodontal disease, which allow harmful bacteria to enter the bloodstream. These bacteria can trigger inflammation in blood vessels, leading to the build-up of arterial plaque — a major cause of heart attacks and strokes.
Dr. Asha Nair, a cardiologist at AIIMS, said:
“People often ignore oral health, thinking it only affects teeth. But gum infections can create a systemic inflammatory response, increasing the risk of atherosclerosis and cardiovascular disease.”
Key Findings of the Study
- People who brushed less than twice a day were 20–25% more likely to suffer a heart attack.
- Regular dental check-ups reduced cardiovascular risk by 15–18%.
- Advanced gum disease was strongly correlated with severe coronary artery blockages.
India-Specific Concerns
India faces a growing burden of both dental and heart health issues. According to the Indian Council of Medical Research (ICMR), over 50% of adults in India suffer from some form of gum disease, and cardiovascular diseases account for 28% of all deaths in the country.
Dentists recommend brushing twice daily, using fluoride toothpaste, flossing regularly, and avoiding sugary foods to maintain oral health. Preventive dental visits every 6 months can also help detect gum issues early and prevent complications.
Preventive Measures
- Brush teeth twice daily with proper technique.
- Use floss or interdental cleaners to remove plaque between teeth.
- Get regular dental check-ups to spot early signs of gum disease.
- Maintain a balanced diet low in processed sugars.
- Quit smoking and tobacco use, as they worsen gum and heart health.
Public Health Implications
The findings highlight the need to integrate dental care into general healthcare policy. Public awareness campaigns encouraging oral hygiene could help reduce India’s dual burden of dental and cardiovascular disease.
Summary:
A major study finds poor oral hygiene significantly raises heart attack risk by increasing inflammation. Regular brushing, flossing, and dental check-ups can lower cardiovascular risk and improve overall health.
