These Oral-B iO Ultimate Clean Replacement Electric Toothbrush Heads are designed to deliver a superior cleaning experience. The unique round brush head surrounds each tooth for a comprehensive clean, while micro-vibrations ensure all surfaces are effectively reached. Ideal for daily use, these heads combine Oral-B's signature oscillating-rotating technology with gentle micro-vibrations to remove up to 100% more plaque than a manual toothbrush. The bristles are strategically designed to reach deep between teeth and along the gum line for comprehensive oral care.
