Use daily after brushing and rinsing with mouthwash. Place the Tri-Angle cleaner at the back of your tongue and pull forward with a gentle skimming motion. Press gently, and pull forward skimming the surface of your tongue. Repeat several times. Rinse with tap water and dry thoroughly after each use to prevent bacteria build-up.
