Good bacteria floss could fight gum disease
NCT ID NCT07149493
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested a special dental floss coated with a probiotic (good bacteria) to see if it could reduce harmful mouth germs and improve gum health. Thirty-three healthy men used the probiotic floss and a placebo floss for two weeks each, with a break in between. Researchers measured plaque, gum bleeding, and levels of harmful bacteria.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Ligilactobacillus salivarius (probiotic) infused into nanofiber dental floss
What this could lead to
If it works, this could point toward a simple way to improve gum health and reduce harmful bacteria using everyday dental floss.
What could go wrong
This is a small, early-stage trial with only 33 healthy men, so results may not apply to everyone. The effect on actual gum disease is still unclear.
