Abstract

A toothbrush includes: a handle shaped and dimensioned to be grasped by a human hand; necks coupled to the handle; bristle supports coupled to the necks; and bristles coupled to the bristle supports. The toothbrush, through the bristles coupled to the bristle supports and the necks, is configured to adapt to a dento-gingival junction and all other changing surfaces encountered during brushing to disrupt plaque. The necks provide (i) resistance above 0.35 kilograms of brushing pressure force and (ii) resiliency below 3.77 kilograms of brushing pressure force. The bristles, the necks, and the bristle supports, in combination, provide (i) resistance above 0.55 kilograms of brushing pressure force and (ii) resiliency below 3.89 kilograms of brushing pressure force.

         10 . The toothbrush of  claim 2 , 
 wherein the necks provide resistance above 0.68 kilograms of brushing pressure force, and    wherein the bristles, the necks, and the bristle supports, in combination, provide (i) resistance above 0.84 kilograms of brushing pressure force.    
     
     
         11 . The toothbrush of  claim 2 , wherein the necks provide (i) lateral resistance above 0.78 kilograms of brushing pressure force and (ii) lateral resiliency below 3.77 kilograms of brushing pressure force.  
     
     
         12 . The toothbrush of  claim 2 , 
 wherein the necks provide resistance above 0.83 kilograms of brushing pressure force, and    wherein the bristles, the necks, and the bristle supports, in combination, provide (i) resistance above 1.05 kilograms of brushing pressure force.
