Cleaning Between Your Teeth Might Do More Than Protect Your Gums.
A 2025 study published in the American Diabetes Association journal Diabetes Spectrum found that adults with type 2 diabetes who cleaned between their teeth at least 3 times per week had better glucose control than those who cleaned less often.
Researchers followed 104 adults with type 2 diabetes and used continuous glucose monitoring (CGM) for 2 weeks. More frequent interdental cleaning was associated with lower fasting blood glucose, more time in the target glucose range (TIR), lower glucose management indicator (GMI), and fewer episodes of high blood sugar.
The study also found lower levels of several inflammatory markers among people with better oral hygiene habits. While this study cannot prove cause and effect, the findings add to growing evidence that oral health may play an important role in overall diabetes care.
