When successful, root canal treatment can significantly reduce inflammation, blood sugar, and cholesterol levels. This promising research from King’s College London suggests that such improvements could lead to a reduced risk of heart disease and type 2 diabetes. offering hope for improved health outcomes
The consequences of this the research is deep. Successful root canal treatment, as suggested by the study, could not only it saves teeth but also significantly reduces inflammation, improves cholesterol levels and lowers blood sugar levels. This could potentially reduce the risk of heart disease and type 2 diabetes.
The study was published in the Journal of Translational Medicine.
First-of-its-kind research on the impact of root canal treatment
Root canal treatment, a dental procedure designed to save a tooth that has been severely damaged or infected, involves several steps. The dentist first removes the infected or damaged pulp inside the tooth, then cleans and disinfects the root canals, and finally fills and seals them. To restore the strength and function of the tooth, a crown is usually placed on it.
In the first research of its kind, a clinical study tracked changes in blood chemistry after root canal treatment for a common dental infection. The infection can allow bacteria to enter the bloodstream and increase inflammation, posing risks to heart health and reducing the ability to control blood sugar levels.
Researchers followed 65 patients from Guy’s and St Thomas’ NHS Foundation Trust for two years after root canal treatment. Scientists analyzed molecules in patients’ blood to reveal how the body processes sugar, fat and other essential substances and how it responds to disease and treatment. They used nuclear magnetic resonance (NMR) spectroscopy to analyze the proteins in the body.
Improved health outcomes after root canal treatment
The team found that successful root canal treatment was associated with:
- Improved glucose metabolism: Blood sugar levels were significantly reduced over two years after treatment.
- Better lipid profiles: Short-term improvements in blood cholesterol and fatty acid levels.
- Reduced inflammation: Key markers of inflammation decrease over time.
- Oral bacteria linked to effects throughout the body: Bacteria are associated with changes in the body’s metabolism.
Lead author Dr Sadia Niazi, Senior Clinical Lecturer in Endodontology, King’s College London, said: “Our findings show that root canal treatment doesn’t just improve oral health – it can also help reduce the risk of serious health conditions such as diabetes and heart disease. It’s a powerful reminder that oral health is deeply connected to overall health.
“Long-term root canal infections can allow bacteria to enter the bloodstream, cause inflammation and raise blood glucose and fat levels – increasing the risk of serious health problems such as heart disease and diabetes. Dental professionals need to recognize the wider impact of these root canal infections and advocate for early diagnosis and treatment.
“We also need to move toward integrated care, where dentists and general practitioners work together to monitor risks through these blood markers and protect overall health. It’s time to move beyond the tooth and take a truly holistic approach to dental care.”
