Abstract
A toothbrush comprising a head, a neck and a handle, the head comprising a readily flexed resilient member having a plurality of bristles arranged on one side thereof, and a rigid member depending from the neck, the resilient member resting on the rigid member and being arranged with an inner array of bristles between outer arrays of bristles on opposite sides thereof, the outer arrays being caused to splay divergingly from the resilient member as a consequence of deformation of the resilient member when the bristles are urged onto a tooth or gum surface.
