Oral-B Pro 3D White replacement brush heads effectively remove food and drink stains from the very first use thanks to an exclusive polishing cup. They feature X-shaped bristles that can clean even hard-to-reach areas that round brush heads cannot reach. The wear indicator signals when the brush head needs to be replaced by changing the bristles from green to yellow. They are compatible with all Oral-B rechargeable toothbrushes except Pulsonic and iO.
