Toothbrush with novel bristle configuration

Abstract

This disclosure provides a toothbrush head and a toothbrush with improved toothbrush bristle configuration comprising different types of bristle filaments in a specified arrangement. Disclosed are toothbrush heads (10) connected to or connectable to a handle (20) to define a head-handle longitudinal direction (L-L) and a widthways direction (W-W) perpendicular to the longitudinal direction (L-L), the head (10) having a bristle surface (12) with a distal end (12A) further from the handle (20), a proximal end (12B) closer to the handle (20), a left side (12C) and a right side (12C), wherein tufts of bristles extend from the bristle surface (12). The tufts of bristles comprise first tufts (14) comprising first bristles (141) with rounded tips and second tufts (16) comprising second bristles (161) which are tapered, wherein some of the first tufts (14) are arranged in a circular nest (15) outermost closest to the distal end (12A), and wherein second tufts (16) are arranged on the left side (12C) and the right side (12D) of the bristle surface (12), with first tufts (14) being arranged between the second tufts (16). Also provided are toothbrushes comprising said toothbrush heads. The toothbrushes achieve excellent plaque removal in all risk areas.
