Tooth brush with four bristle groups

Abstract

A toothbrush for use on humans and pets, comprising a toothbrush head with each end curved upward at 90 degree angles; said toothbrush head further comprising four sets of soft bristles. Three sets of bristles are attached to the front face of the brush head, with two sets positioned opposite each other on each upward curved end of the head and the third set of bristles positioned in the center, perpendicular to the other two sets, thereby providing coverage of the mesial, distal and occlusal surfaces of the teeth simultaneously. The fourth set of bristles is attached to the back side of the toothbrush head, thereby cleaning and massaging the opposing teeth at the same time that the other three sets of bristles are doing the primary cleaning. The toothbrush handle is attached to the center of the head for ease of use and the ability to reach the back molars.

 first and second sets of bristle tufts fixedly attached to each upwardly turned end of said base, wherein said first and second sets of bristle tufts extend inward toward each other,  
 a third set of bristle tufts fixedly attached to a center of said base and extending perpendicular to said first and second sets of bristle tufts.  
   
     
     
         2 . The toothbrush according to  claim 1 , wherein said toothbrush head further comprises a fourth set of bristle tufts fixedly attached to said base opposite said third set of bristle tufts, whereby said toothbrush simultaneously engages the mesial, distal, and occlusal surfaces of the teeth during the cleaning process.  
     
     
         3 . The toothbrush according to  claim 1 , wherein said base is approximately 1⅛ inches long.

 a base protruding laterally from said handle to opposing ends, the ends being angled upward from said base,  
 first and second sets of bristle tufts fixedly attached to each upwardly turned end of said base diametrically opposite each other, wherein said first and second sets of bristle tufts extend inward toward each other,  
 a third set of bristle tufts fixedly attached to a center of said base and extending perpendicularly between said first and second sets of bristle tufts, and  
 a fourth set of bristle tufts fixedly attached to said base opposite said third set of bristle tufts;  
   whereby said toothbrush simultaneously engages the mesial, distal, and occlusal surfaces of the teeth during the cleaning process.    
     
     
         12 . The toothbrush according to  claim 11 , wherein said base is approximately 1⅛ inches long.
