Each Oral-B toothbrush head's design is inspired by professional dental tools. The Oral-B Professional Floss Action replacement Electric 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.
