Abstract: A toothbrush for cleaning selected teeth does so with the aid of teeth opposed to the selected teeth and includes groups of bristles extending altitudinally from an upper face of a bristle support and bowed to curve laterally outwardly in directions away from one another, the bristle support including a concave support surface on a lower face of the bristle support for engaging the opposed teeth and guiding the bristle support through rocking motions which enable bristles in the groups of bristles to sweep over the selected teeth and effect cleaning of the selected teeth, and between adjacent teeth, while also messaging the gum adjacent the selected tooth. Further support surfaces on the bristle support are spaced transversely from the upper face and guide the bristle support during further cleaning and messaging manipulations.
