The Oclean UW03 W02 replacement brush heads from the Ultra White series come in a pack of two and are designed for adults using any Oclean electric toothbrush model. These white, oval-shaped heads feature a central polishing rubber ring specifically intended to remove surface stains and whiten teeth, which helps reduce stains by 38% more than standard options. To ensure a thorough clean, the heads incorporate FlexFit technology and an innovative 5-degree design that allows the bristles to reach deeper below the gum line and into hard-to-access areas. The body is coated with an impact-absorbing rubber layer, providing a gentler experience during use while maintaining the effectiveness of the medium-to-firm bristles.
