For those who do not consistently use dental floss, the AirFloss Pro is the easiest way to effectively clean between teeth. The AirFloss Ultra can be used with mouthwash or water and is clinically proven to be as effective as dental floss for healthy gums. It removes up to 99.9% of plaque in treated areas. The Philips Sonicare AirFloss Ultra has been shown to be as effective as dental floss and improves gum health in just two weeks. By gently removing plaque residues that brushing alone does not eliminate, the Philips Sonicare AirFloss Ultra helps prevent cavities between teeth. The clinically proven combination of air and microdroplet technology cleans gently and effectively between teeth and along the gum line. With the AirFloss Ultra, you can clean your entire mouth in less than 60 seconds a day. Simply choose your spray frequency (single, double, or triple) and hold down the activation button for continuous automatic sprays. When you release the button, the device switches to manual mode. The new powerful AirFloss Ultra nozzle enhances the effectiveness of the air and microdroplet technology for greater efficiency than ever before. Cleaning between teeth is crucial for overall oral health. AirFloss makes it easy to thoroughly clean between teeth and make healthy oral care a habit. Fill your AirFloss with mouthwash for an ultimate deep-clean feeling and antimicrobial cleaning. You can adjust the powerful spray of the AirFloss Ultra to your preferences. Choose whether a single, double, or triple spray is released with each press of the activation button.
