A toothbrush comprising a brush head and a handle, the brush head carrying three rows of bristle tufts which form a generally T-shaped pattern when viewed from above. A first and second row of tufts extend angularly toward each other and intersect in a plane which runs generally parallel to the longitudinal axis of the brush. A cross row of tufts at the end of the brush head inclines toward the other tufts to from the T-pattern. The handle is specially contoured near the brush head to facilitate movement of the brush over the teeth.
A toothbrush including a handle having an upper surface, a lower surface, a proximal end and a distal end with a head portion having a plurality of bristle tufts integral thereto and an intermediate portion therebetween. An L-shaped portion having a horizontal extent and a vertical extent being formed integral with the horizontal extent and the proximal end of the handle. A gripping portion being formed along the intermediate portion of the handle on the upper surface and capable of supporting a thumb of a hand. A distal widened V-shaped portion having a pair of extents with a distal seat therebetween, each extent having a second end integral with the distal end and a first end integral with the gripping portion to form a proximal widened V-shaped portion with a proximal seat, the extent between the distal seat and the proximal seat being capable of supporting an index finger of the hand while the intermediate portion rest in the palm of the hand.
An improved toothbrush having a longitudinally extending base handle member with an upper surface and a lower surface and having opposing side surfaces, such base handle member having a longitudinal axis and a handle end and a brush end, with a first group of brush bristle members affixed to the brush end, which first group of brush bristle members extend outwardly from such brush end, with a separate and second group of said brush bristle members extending downwardly from the lower surface of the base handle member in a direction perpendicular to such lower surface and an additional group of brush bristles extending from a portion of base handle member in a direction different from the directional disposition of the first group.
A device for removal of dental plaque from the furca, cemento-enamel junction, and gingival pockets in between two adjacent teeth, the device having a dental arm with a detachable dental brush having a malleable spine supported substantially perpendicular from the arm, the arm imparting a tiny mechanical vibratory action from a motor driving an eccentrically mounted cylindrical weight through contact of the brush with the furca, junctions and pockets in between the adjacent teeth. The brush having a conical shape defined by a cross section representing an isoceles triangle having an apex angle of approximately 30.degree. wherein the surface of the brush is contourable and the bristles are splayed by the tiny vibratory action into the furca, junctions, and pockets.
A toothbrush whose tufts comprise three distinct groups of rows, with each row oriented transversely to the longitudinal axis of the head. The tufts of the first group are the shortest. The endmost tufts on each row of the second kind tilt laterally outwardly by about 12 degrees. The tufts of the third group are nearest the end of the head farthest from the handle and diverge from each other. In one embodiment, each tuft of the third kind tilts laterally at an angle of about 30 degrees and forwardly at about 14 degrees. In a first embodiment, each row of the first group comprises a single, wide tuft. In a second embodiment, each row of the first group has a plurality of laterally spaced round tufts. In a third embodiment, each row of the first group comprises a plurality of laterally spaced quadrangular tufts. All of the tufts may also be considered as defining four functional groups of tufts, with each of these four groups performing a specific function during brushing. The arrangement and orientation of the tufts yields a uniform cleaning action substantially independent of brushing direction or technique.
