Ordo Sonic+ Replacement Brush Head - Rose Gold - Pack of 4. These brilliant brush heads have been developed after years of research by Ordo's oral hygiene engineers to be the ultimate brush head for all mouth types. The slim head allows for excellent manoeuvrability, while the alternate bristle heights ensure a deeper clean. A silicone textured back is designed to massage the inner surfaces of your gums, and a polishing element helps to whiten your teeth through a gentle polishing action. The brush heads feature DuPont bristles that are soft and individually rounded, providing a clean that is gentle on gums and tooth enamel, yet tough on plaque. Recommended by dentists, the silicone polishing element works to help remove surface stains. Sonic pulse technology utilizes fluid dynamics to clean deep between teeth, removing more plaque than a manual toothbrush. Our brush heads are easily interchangeable with a simple push-fit design. Not suitable for children under 8 years old.
