Patent ID: 8677542

Claim:
A toothbrush head attachment equipped with a combination of bristled tufts which when operationally driven by a power source and a complete brushing of tooth surfaces including interproximal tooth surfaces and subgingival areas therewith serves to effectively dislodge bacteria of a biofilm adhering about the tooth surfaces allowing for an effective antimicrobial agent treatment thereof to kill the dislodged bacteria and-thereby provide the tooth surfaces substantially free from surviving bacteria; said attachment comprising a drive system equipped to counterrotate adjacently positioned bristled tufts of the combination about a central tuft axis for each of the bristled tufts, said combination of bristled tufts being characterized as comprising a plurality of short bristled brush tufts and a plurality of long bristled brush tufts positioned in an alternating sequence of said short bristled tufts and said long bristled tufts in a paired rowed arrangement of a first row arrangement with a second row arrangement having a sequential mating of said long bristled tufts and said short bristled tufts such that each sequence of the short bristled tufts and the long bristle tufts in the first row arrangement and the second row arrangement will laterally and sequentially mate with each other, said long bristled brush tufts being further characterized as having a substantially longer and narrower tuft size than the short bristled tufts, with the long bristled tufts being comprised of bristled filaments of a sufficient length, sufficient cross-sectional dimensional stiffness and a sufficient number of the long bristled filaments of a tuft cross-sectional size so as to enable the long bristled brush tufts upon operational use to independently penetrate onto and dislodge the biofilm from the interproximal tooth surfaces and the subgingival areas, said short bristled brush tufts being characterized as being comprised of a number of short bristled filaments of a substantially softer and shorter filament structure than the long bristled filaments, with said short tuft bristled tufts providing a sufficient cross dimensional tuft size and a filament structure to operationally permit the short bristled tufts to dislodge the bacteria of the biofilm about facial tooth surfaces and lingual tooth surfaces while also providing sufficient spacing between adjacently positioned long bristled brush tufts to permit the long bristled tufts upon operational use to independently penetrate onto the interproximal tooth surfaces and the subgingival areas and thereby dislodge the bacteria therefrom so as to permit the effective antimicrobial agent treatment thereof.
