A toothbrush head having an undulating surface with at least one more displaced part and at least one less displaced part and with bristles having a triangular cross section extending from a more displaced part of the bristle face.

Toothbrush

A dental cleaning implement such as a toothbrush, having longitudinally disposed first and second parts flexibly joined together. Between the first and second parts is a rotatable member such that when the implement bends the first parts adjacent to the member bear upon the member. The rotatable member has circumferentially disposed relatively softer and harder regions, so that as the member is rotated the parts can be caused to bear compressibly upon selected softer or harder regions.

A toothbrush having a head which carries a dental cleaning tool, and a grip handle, the head and handle being disposed along a longitudinal head-handle axis, the toothbrush having a resiliently flexible structure which can resiliently bend under the action of toothbrushing pressure and having adjustment means comprising a longitudinally moveable stiffening member which can be moved longitudinally into greater or lesser engagement with the resiliently flexible structure.

A toothbrush having a resiliently flexible composite region between its head and handle which comprises one or members of generally triangular shape in section either made of a resilient elastomeric material different to the hard plastic material of the toothbrush head and handle, or made of a hard plastic material.
