Abstract
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.
