  • Soothes discomfort during treatments.
Main Highlights
  • Oncology Specific Formulation - Prevention’s’ over-the-counter (OTC) oncology mouth sore mouthwash has been formulated for use by patients going through chemotherapy and radiation treatment. These treatments can result in uncomfortable mouth sores, ulcers, dry mouth, and other oral complications. This gentle alcohol free mouthwash helps soothe, alleviate and control these side effects, while helping to retain moisture and protect the mucosal lining. The perfect mouth sores treatment for temporary relief of minor discomfort and irritated areas in a sore mouth and sore throat.

Our mouthwash has no artificial colors or SLS, is alcohol-free and fluoride-free, making it a safe and gentle rinse for oral health support while undergoing treatment.
  • Formulated for Sensitive Mouths - Oncology treatments can lead to oral taste sensitivity and irritation of mouth and throat, so our Oncology mouthwash rinse was created with the goal of minimizing irritants found in other rinses. Our highly effective oral rinse mouthwash features a low-concentration hydrogen peroxide to oxygenate under the gum line to support and maintain gum health, and glycerin to soothe and protect the oral cavity. It acts as a medicated mouthwash to provide temporary pain relief for irritated areas in the mouth, lips and throat, while rehydrating and moisturizing to alleviate dry mouth symptoms.
  • Safe & Easy To Use - This alcohol free mouth wash is safe for all ages over 2 years old and easy to use. Early and regular use of this oral mouthwash will aid in protecting against dry mouth and uncomfortable oral complications. Our rinse is a convenient alternative or supplement for magic mouthwash and may be used in conjunction with other Oncology treatments. We recommend rinsing 3-5 times a day when undergoing chemotherapy and/or radiation treatments.
  • Prevention Health Sciences - Good oral health begins with Prevention! Our complete line of dental rinse and mouthwashes are free of harsh chemicals and ingredients, always naturally flavored, alcohol-free and without any SLS or artificial colors.
