Abstract
An oral hygiene appliance includes a base on which upstands a cabinet having top, front and rear vertical walls. A pair of recesses are formed in either side of that front wall. A plurality of seats within those recesses are each receptive of a jet tip. An inlet is defined in the top wall. A cover is shaped to envelope the cabinet over the recesses and the inlet with the cover being invertable to serve as a reservoir. Disposed within the cabinet is a pump responsive to a pressure control for delivering water received from the inlet. Seated toward one end of the base is the lower end of an elongated electric toothbrush body. Individual brushes are seated in the base around the body and those brushes ordinarily to the rear of the body are elevated on a pedestal. At the opposite end of the base is a well in which is seated the lower end of a handle in which a faceted lower end of one of the jet tips may be captivated. A pressure control unit cooperates with the pump assembly to guard against excessive pressure and permit easy control of the level of pressure delivered from the jet tip mounted in the handle.
