The Oclean Ultra White (UW02 B02) replacement brush heads are designed specifically for Oclean Ultra Series sonic electric toothbrushes to help you maintain a brighter smile. These black, oval-shaped heads feature high-quality DuPont bristles and integrated polished rubber rings that increase friction to effectively lift surface stains, reducing them by 38% more than the Professional Clean variant. To ensure a thorough clean, the bristles are arranged in an innovative 5° angle, allowing them to reach deeper below the gum line where plaque often accumulates. This set includes two firm-to-medium stiffness heads, providing a balanced scrubbing action that suits those looking for a more intensive cleaning experience during their daily oral care routine.
