ABSTRACT:
A toothbrush with independently mobile bristles comprises a toothbrush body with a handle section, a head section and a neck section, with a long axis there through. A plurality of individual, linear slots extends from a top surface of the head section and terminates there within. The individual slots are angled to the long axis of the toothbrush body. A bristle assembly is movably positioned in each slot of the head section with a bristle group extending exterior to the top surface thereof. When brushing teeth, movement of the toothbrush body in a first direction, parallel with the long axis thereof, causes movement of the bristle assemblies in a direction essentially perpendicular to the long axis of the toothbrush body. Movement of the toothbrush body in the opposite direction causes movement of the bristle assemblies in an opposite direction, also essentially perpendicular to the long axis of the toothbrush body.
