Abstract: An adjustable head toothbrush includes a one piece molded head and handle defining an interior cavity within the head portion. An integral molded hinge coupled member is supported within the cavity and is moveable in response to a moveable slide to elevate a portion of the assembly and alter the configuration of bristles within the toothbrush. In one embodiment, a slide is coupled to a link member by an arm and a pair of pivotal members are coupled to a moveable bristle support. In an alternate embodiment, a bristle support is hingeably coupled to a pivoting member which in turn is caused to pivot in accordance with the position of a moveable slide coupled to the toothbrush handle.
