Abstract:
A method of gently cleaning teeth and soft tissue in the oral cavity comprising brushing with an abrasive containing substance in combination with a toothbrush having improved cleaning efficiency and abrasion efficiency, wherein:(a) the average particle size of said abrasive is between about 3 and about 25 microns,(b) said toothbrush comprises a multiplicity of groups of multichanneled bristles, wherein lateral surfaces of said bristles contain at least two longitudinal channels extending substantially along the longitudinal length of each bristle, with said channels being of a depth sufficient to entrap an effective quantity of said abrasive, and(c) wherein the contact between said abrasive entrapped in said channels and said teeth and soft tissue surfaces is improved during brushing, resulting in a cleaning efficiency coefficient of at least about 1.5 and an abrasion efficiency coefficient of at least about 1.5, without adversely effecting the soft tissue in the oral cavity.
