Taking care of your teeth does more than protect your oral health—it may also benefit your overall wellbeing. A recent study by King’s College London suggests that treating dental infections, such as through root canal procedures, can reduce inflammation linked to heart disease.
Published in the Journal of Translational Medicine, the study followed 65 patients from Guy’s and St Thomas’ NHS Foundation Trust in London over two years. Researchers monitored blood chemistry before and at four intervals after root canal treatment, analyzing markers for fat and sugar metabolism, cholesterol, fatty acids, and inflammation.
The results showed improved glucose metabolism, better blood cholesterol and fatty acid profiles, and reduced inflammation. These factors are associated with cardiovascular health, suggesting that addressing oral infections could lower the risk of serious conditions such as heart disease and diabetes.
“Root canal treatment doesn’t just improve oral health—it may also help reduce the risk of serious health conditions,” said Dr. Sadia Niazi, senior clinical lecturer in endodontology at King’s College London. “This is a powerful reminder that oral health is deeply connected to overall health.”
Globally, untreated dental disease affects 3.7 billion people, highlighting the need for accessible dental care. The researchers recommend that oral health become an integral part of general healthcare. Niazi emphasized: “Your mouth is the main gateway to your general health. Regular dental check-ups and early treatment of disease are crucial.”
For patients facing root canal treatment, the procedure may offer benefits that extend well beyond oral health, potentially improving long-term wellbeing.
