Because brushing and flossing only cover 25% of the mouth’s surfaces, plaque biofilm can still be present in the mouth. Adding a rinse to an everyday oral care routine can penetrate deep into plaque biofilm and kill the remaining bacteria. This complete oral care routine that incorporates brushing, flossing, and rinsing offers a virtually 100% whole mouth clean®.38
