Abstract: A toothbrush assembly having a handle component and a brush component which in the storage mode of the assembly is housed within the handle component. In the brushing mode, the brush component is attached to the handle component and projects therefrom. The brush component is formed by a shank having a brush head anchored thereon, the shank terminating in a mounting plug. The handle component is formed by a hollow body having an elongated belly section in whose cavity the brush component is storable, the belly section flowing into an enlarged annular shoulder leading to a neck section adapted to socket the plug of the brush component. The handle body is contoured to define a concave fore depression at the junction of the shoulder and the neck section, and a concave aft depression at the junction of the shoulder and the belly section.
