ABSTRACT:
An oral care implement or toothbrush includes a head and a tooth cleaning element for enhanced cleaning and whitening of the teeth. The tooth cleaning element has a base corrected to the head. The base has structure in the form of a concave surface facing a distal region of the head such that dentifrice applied to the head is adapted to be directed towards the distal region of the head. A protrusion extends from the concave surface towards the distal region of the head. The head may include a plurality of concave surfaces that are substantially aligned along a longitudinal axis of the head, and protrusion extends from the curved surface.
