Listening is the next step in ensuring a healthier mouth. Focusing on and sticking to good oral care habits includes regular visits to your dentist and a daily regimen of brushing, flossing, and rinsing with Listerine. The truth is that brushing reaches 25% of your mouth. Listerine cleans practically 100%. The power of the swish fights bad breath bacteria throughout the mouth, including the teeth, tongue and gums. Use Listerine mouthwash twice a day to achieve its deep cleaning efficacy. After all, bad breath germs are in your mouth all day, every day, and rinsing twice a day provides 24-hour germ protection. For Listerine Rinse to reach its full potential, use as directed and rinse vigorously for 30 seconds twice daily.
