Root canal treatment could significantly lower blood sugar levels, study suggests
A new study reveals that root canal treatment can have far-reaching health benefits, extending beyond just the treated tooth. Researchers followed 65 patients from Guy’s and St Thomas’ NHS foundation trust in London for two years after root canal treatment, analyzing their blood molecules to understand how they process sugar, fat, and other substances.
The findings are particularly important for global health, as chronic tooth infections often go untreated. According to the World Health Organization, 3.7 billion people globally live with untreated oral disease. Given the broader health impact of tooth infections, oral health should be integrated into a patient’s general healthcare, Niazi said.
The study found that root canal treatment led to significant improvements in blood sugar levels over two years, suggesting that ridding the body of problematic bacteria could help protect against type 2 diabetes. Additionally, dentists observed improvements in patients’ blood cholesterol and fatty acid levels, both of which are associated with heart health. The treatment also reduced markers for inflammation, a driver for cardiovascular disease and other chronic conditions.
"Our oral health is connected to our general health," said Dr. Sadia Niazi, a senior clinical lecturer in endodontology at King’s College London. "We should never look at our teeth or dental disease as a separate entity."
The research was published a week after a clinical trial at University College London found treatment for severe gum disease could prevent arteries from becoming clogged, reducing the risk of coronary heart disease and stroke. The treatment reduced inflammation caused by the gum disease, further highlighting the connection between oral health and overall well-being.
"It’s not about treating the single tooth," Niazi said. "This has long-term benefits on the general health of the patient, particularly the risk of chronic conditions like heart disease and diabetes."
"People must understand that your mouth is the main gateway to your general health," she added. "Looking after your oral health and doing regular checkups with your dentist and getting disease treated early is the best course of action."
The study emphasizes the importance of addressing oral health as part of overall healthcare. By treating tooth infections and managing oral health, individuals can potentially reduce their risk of chronic diseases and improve their overall health.
