Root canals may lower heart disease and diabetes risk by reducing harmful bacteria and inflammation, a new study finds.

A new study links root canal treatment to lower risks of heart disease and diabetes, showing improved blood sugar control, reduced inflammation, and better cholesterol levels in 65 patients over two years. Researchers suggest removing infected tooth pulp may reduce harmful bacteria in the bloodstream, lowering systemic inflammation tied to chronic conditions. Findings, published in the Journal of Translational Medicine, support growing evidence that oral health affects overall well-being, urging integration of dental and medical care.
