Toothbrush

A manual toothbrush comprising an elongate handle with a head at one end of the handle, the head and handle defining a toothbrush longitudinal direction, oral hygiene elements extending from a surface of the head in a bristle direction transverse to this longitudinal direction, wherein;

• the oral hygiene elements comprise:
• either (A) first bristle filaments disposed in tufts having a circular envelope, the tufts being arranged in polygons with a tuft at each apex of the polygon, the polygons being nested together in at least one nest of polygons, plural nests of polygons being arranged sequentially longitudinally on the surface of the head, the surface comprising a surface region proximal to the handle and a surface region distal from the handle the proximal and distal surface regions forming an angle less than 180° between them, two nests being located respectively on the proximal and distal surface regions, or:
• (B) first bristle filaments disposed in tufts having a circular envelope, and a second type of oral hygiene element different from the first bristle filaments and being:
• either second bristle filaments also disposed in tufts having a circular envelope and having one or more characteristic different from the first bristle filaments selected from a different length, or incorporating an additional tooth-polishing ingredient relative to the first bristle filaments:
• or:
• elastomer oral hygiene elements optionally incorporating an additional tooth-polishing ingredient,
• and wherein the first bristle filaments and the second type of oral hygiene element are arranged on the surface in respective nested polygons of the oral hygiene elements, with an oral hygiene element at each apex of the polygon, and comprising an outer polygon of first bristle filaments, and an inner polygon of first bristle filaments, and between these outermost and inner polygons an intermediate polygon of the second type of oral hygiene elements.
