A new scientific study has found that getting a root canal may do more than just relieve tooth pain — it could also help improve blood sugar control in people with diabetes.
Researchers discovered that treating infected or inflamed teeth reduces chronic inflammation in the body, which plays a major role in raising blood sugar levels. According to the study, patients who received root canal treatment showed better glycemic control within a few months compared to those who left dental infections untreated.
Experts say dental infections can worsen diabetes and make blood sugar harder to manage. When the infection is removed through a root canal, the body’s inflammatory response decreases, leading to more stable glucose levels.
Health professionals are now urging diabetic patients not to ignore dental symptoms such as persistent toothache, swelling, sensitivity, or gum infections. Early treatment, they say, can protect both oral health and overall metabolic health.
The study highlights an important connection between oral hygiene and chronic diseases, suggesting that routine dental checkups may play a key role in managing diabetes effectively.
