Can a simple mouthwash help fight gum disease? new study aims to find out
NCT ID NCT07257887
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a hydrogen peroxide mouth rinse (OROXID®) can improve gum health when used alongside standard dental cleaning. About 90 adults with moderate-to-severe gum disease will use either a 1.5% or 3% rinse or a control rinse for 12 weeks. The goal is to see if it reduces pocket depth and bleeding compared to standard care alone.
