A breakthrough study from King’s College London has revealed something truly remarkable about a dental treatment millions of people receive every year. While root canal therapy has long been understood as a way to relieve pain and save an infected tooth, new scientific evidence suggests its benefits may go far beyond the mouth — potentially helping reduce the risk of serious conditions like heart disease and type 2 diabetes.
This research is not just about dental health — it highlights a powerful link between our oral health and our overall metabolic and cardiovascular well‑being, reinforcing the idea that what happens in our mouth truly matters for the health of our entire body.
🦷 What Did the Study Investigate?
Scientists followed 65 patients who underwent successful root canal treatment to fix a common infection called apical periodontitis — a condition where bacteria deeply infect the root of a tooth and surrounding tissues. Left untreated, this infection can allow bacteria to enter the bloodstream, causing systemic inflammation — a known contributor to heart disease, poor blood sugar control, and other chronic health problems.
