If the thought of a root canal makes you anxious, there may be a silver lining. Research from King’s College London indicates that treating tooth infections with a root canal could bring benefits far beyond a healthy smile. The study suggests that addressing dental infections may help reduce the risk of diabetes, improve heart health, and lower inflammation in the body.

What did the study find?

The first-of-its-kind research tracked 65 patients with common tooth infections (apical periodontitis) over two years. After successful root canal treatment, patients showed:

Lower blood sugar levels: Significant drops in glucose over two years, suggesting protection against type 2 diabetes.

Improved cholesterol and fats: Short-term improvements in blood lipid levels, linked to heart health.
