Good bacteria vs. gum disease: could probiotics help diabetics?
NCT ID NCT07598656
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether applying a probiotic (Lactobacillus reuteri) directly into gum pockets, alongside standard deep cleaning, improves gum health in people with type 2 diabetes. Fourteen adults with moderate to severe gum disease and controlled diabetes took part. Each person received both the probiotic and a placebo (distilled water) on different sides of the mouth, and gum measurements were tracked for 6 months.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Lactobacillus reuteri probiotic
What this could lead to
If it works, this could point toward a simple, natural add-on treatment to improve gum health in people with diabetes.
What could go wrong
This is a very small, early study with only 14 participants. The probiotic may not provide extra benefit over standard care, and results may not apply to everyone.
