With the AirFloss, cleaning your entire mouth takes just several seconds. Simply press the button once for a single burst, then move and repeat. To use the auto-burst feature, hold down the button and move the guidance tip from space to space. It will automatically burst every second. The slim angled nozzle and guidance tip make finding the correct placement easy. Just slide along the tooth's surface near the gum line until the tip fits into the groove between the teeth. Interproximal cleaning is very important to overall oral health. AirFloss is an easy way to clean deeper between teeth, helping to form a healthy habit. By gently bursting away plaque that brushing missed, Sonicare AirFloss helps prevent cavities from forming in the spaces between your teeth. Designed to be easy to maneuver in tight spaces, AirFloss has a comfortable ergonomic handle and a non-slip grip.
