A toothbrush and plaque scraper is disclosed for an oral cavity. A rigid handle, adapted to be grasped by a user, has a rigid base portion at a first end of a handle, extending away from the handle and having a top surface, at least one side surface and a bottom surface wherein the top, bottom and at least one side surface each comprise substantially uniform surfaces. Bristles are mounted to the top surface and adapted to be placed in the oral cavity for brushing teeth and extending in a first direction. A single rigid blade converges to an edge in a second direction substantially different from the first direction, contiguous to at least one of the at least one side surface and the bottom surface.
