But did you know that brushing alone on average, only removes 42% of accumulated plaque each time? Adding a LISTERINE® mouthwash that contains fluoride to your oral hygiene routine can help strengthen teeth, reduce plaque, and prevent tartar, the major causes of gum disease. Reaches where brushing can’t Brushing just your teeth only targets 25% of the mouth*. Mouthwash targets virtually 100% of the mouth. Adding a LISTERINE® mouthwash into your oral care routine can penetrate deep into plaque and kill up to 99% of germs left after brushing. LISTERINE® Total Care mouthwashes can also reduce plaque by up to 56% more than brushing alone. Maintains healthy gums Mouthwash, such as LISTERINE® Total Care, can reduce plaque and maintain healthy gums. Helps freshen breath LISTERINE® Total Care kills up to 99% of plaque and bad breath-causing germs left behind after brushing and helps provide up to 24-hour fresh breath protection. Essential oils Essential oils are at the core of LISTERINE® mouthwash formulations. We use a unique four-ingredient formula of thymol, eucalyptol, menthol, and methyl salicylate. These ingredients penetrate the biofilm to help reduce plaque and kill bacteria. Mouthwashes containing essential oils can also be a good option for combating bad breath. They can help freshen breath by killing bad breath-causing germs. This information has been provided by LISTERINE® - an official partner of National Smile Month 2025. Manage Cookie Preferences
