A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user. A contact member for engaging the teeth of the user is moveable relative to the nozzle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of contact member relative to the nozzle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

A combination electric toothbrush and water irrigation device that combines a battery powered water irrigation device with a vibrating electric toothbrush, both of which are housed in a self-contained compact hand-held device. The pump for the water irrigation device and the DC motor with an off-center weight are contained within the handle of the toothbrush. A slide out water reservoir allows the user to fill the extended handle portion with water. A flexible water inlet tube is capable of compressing when the water reservoir is in the storage position. A weight fixed to the end of the inlet tube causes the tube to bend via gravity enabling it to be in constant contact with water while the handle is held at various angles. An LED at the underside of the pump housing illuminates the water contained within the transparent water housing.
