Colgate Peroxyl Medicated Mouthwash is a ready-to-use oral cleansing rinse containing hydrogen peroxide 1.5% w/v, specially formulated to help cleanse and soothe minor mouth and gum irritations. This medicated mouthwash works through a unique oxygenating cleansing action that releases oxygen on contact, helping to remove debris and kill bacteria to support healing of canker sores, minor wounds, gum inflammation, cheek bites, and irritation from braces or dentures. Colgate Peroxyl is ideal for short-term relief of oral discomfort and can assist in maintaining oral hygiene after dental procedures.
