6.3 Flossing Technique
- Lean over a sink and place the jet tip in your mouth, aiming the stream at your gumline at a 90-degree angle.
- Close your lips slightly to prevent splashing, but allow water to flow from your mouth into the sink.
- Start with your back teeth and work your way forward, pausing briefly between teeth.
- Follow the gumline and clean both the front and back surfaces of your teeth.
- The 360° rotatable jet tip allows for easy access to all areas of your mouth.
- Continue until you have cleaned all areas or the water tank is empty (approximately 75 seconds of continuous use).
