Mouthwash showdown: can hydrogen peroxide rinse beat gum disease?

NCT ID NCT07270705

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a hydrogen peroxide mouth rinse called OROXID can help treat gingivitis, a common gum inflammation. About 90 adults with mild gum disease will use the rinse twice daily for 4 weeks, alongside regular brushing. Researchers will measure changes in gum inflammation, plaque, and bleeding to see if it works better than brushing alone.
