Abstract
Abstract A toothbrush with a jet nozzle at its end extending angularly toward the same side as the brush bristles and having a detachable handle, a flexible fluid duct from a fluid source, such as an adjustable hot and cold water spigot, and a valve for regulating the fluid for the jet, which valve may be at the source and/or in the handle. The handle may be hollow for connection to the flexible duct, or may be an electric or mechanical toothbrush handle, or a water jet or water pick handle. A source of dentrifrice and/or disinfectant may be provided either in the jet brush attachment, in its handle, or from a reservoir connected by a separate duct to the jet brush attachment.
