         10 . The tooth cleaning apparatus of  claim 1  wherein the at least two brush heads form a generally S-shape. 
     
     
         11 . The tooth cleaning apparatus of  claim 1  wherein the brush segment comprises a flexible member arranged between the at least two brush heads, a semi-flexible member arranged between the at least two brush heads or a rigid member arranged between the at least two brush heads. 
     
     
         12 . The tooth cleaning apparatus of  claim 1  wherein the head portion is releasably secured to the handle portion. 
     
     
         13 . A tooth cleaning apparatus adapted to clean a set of teeth of an animal, the apparatus comprising:
 a handle portion; and,   a head portion comprising a brush segment having at least two brush heads, each of the at least two brush heads comprises a plurality of brushes adapted to simultaneously clean a quadrant of the set of teeth, a distal brush head of the at least two brush heads comprises a concave plurality of brushes and a proximal brush head of the at least two brush heads comprises a convex plurality of brushes.   
     
     
         14 . The tooth cleaning apparatus of  claim 13  wherein the distal brush head comprises at least one column of brushes and the at least one column of brushes comprise nylon bristle tufts. 
     
     
         15 . The tooth cleaning apparatus of  claim 13  wherein the proximal brush head comprises at least one column of brushes and the at least one column of brushes comprise nylon bristle tufts. 
     
     
         16 . The tooth cleaning apparatus of  claim 13  wherein the set of teeth of the animal comprise back molars and the handle portion forms an angle of at least thirty degrees relative to a midline of a mouth of the animal as the at least two brush heads are applied to the back molars. 
     
     
         17 . The tooth cleaning apparatus of  claim 13  wherein the set of teeth of the animal comprise back molars and the handle portion forms an angle of at least forty degrees relative to a midline of a mouth of the animal as the at least two brush heads are applied to the back molars. 
     
     
         18 . The tooth cleaning apparatus of  claim 13  wherein the at least two brush heads form a generally S-shape.
