3D Action for Tooth-by-Tooth Cleaning. Each Oral-B toothbrush head’s design is inspired by professional dental tools. The Floss Action toothbrush head has MicroPulse bristles to clean deep between teeth for outstanding plaque removal. While it does not replace flossing, it does provide a floss-like clean, as well as a superior whole mouth clean compared to a regular manual toothbrush. The Floss Action head works with unique Oral-B technology that oscillates, rotates and pulsates, allowing the bristles to surround each tooth for an amazing, tooth-by-tooth clean.
