Abstract

A toothbrush is provided that can easily and effectively remove dental plaque on molars in the deepest part of the mouth, in interdental spaces and on inner surfaces of the teeth. The bristle tips form three brush surfaces (1-3). The first brush surface (1) is adjacent the free end of the brush and extends upwardly from the free end to define a first bristle peak. The second brush (2) surface extends downwardly from the first bristle peak towards the brush head (40). The third brush surface (3) extends upwardly from the second brush surface to a second bristle peak adjacent to the attached end of the brash head. The second brash surface and the third brush surface intersect to form a bristle valley located below the first bristle peak and the second bristle peak. The toothbrush preferably comprises six to ten rows of bristle tufts (25-32).
