Friendly bacteria may help fight gum disease in diabetics
NCT ID NCT07652255
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a probiotic (Lactobacillus reuteri) to standard deep-cleaning treatment for gum disease can improve gum health and blood sugar levels in adults with diabetes. Participants receive either the probiotic or a placebo (salt water) applied directly into gum pockets after cleaning. The trial measures changes in gum bleeding, pocket depth, and HbA1c over three 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 effective, this probiotic could become a simple, low-cost addition to standard gum disease treatment for people with diabetes, potentially improving both oral health and blood sugar control.
What could go wrong
This is a very small, early-stage trial with only 5 participants, so results may not apply to everyone. The probiotic may offer no extra benefit over standard care, and individual responses can vary.
