<p>A toothbrush (10) which is anatomically designed and constructed to effectively and efficaciously remove plaque or calculus from the inaccessible interproximal spaces between adjacent teeth, and at the same time gently massage the gingiva and effectively clean the teeth. The toothbrush (10) includes a unique and novel bristle arrangement at one end of an offset handle (14). The bristles are arranged in tufts (22) embedded in and anchored to a toothbrush head (12) which is integrated with the handle (14) in a conventional manner. The bristle tufts (22) being arranged in twelve transverse or lateral rows (1-12) with each transverse row including four tufts of bristles except for the outermost transverse row (1) which includes only two tufts of bristles (22). The odd numbered transverse rows of tufts of bristles (1,3,5...) are all the same length and the even numbered transverse rows of tufts (2,4,6...) are of a length less than the odd numbered transverse rows of tufts (1,3,5...). The even numbered transverse rows of tufts (2,4,6...) progressively increase in length toward the handle. All the bristles and tufts (22) are rounded to prevent injury to the gingival gum area. The other end of the handle is provided with an accessory brush (15) in the form of a tuft of bristles (34) to reach areas which may require individual additional or special attention due to teeth positioning and is especially useful for removing food debris and plaque from gingival pockets to assist in preventing periodontal disease. <IMAGE></p> |
