Abstract: A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid to the oral cavity of a user. A drive unit drives movement of a bristle carrier relative to the handle. The fluid reservoir extends about at least part of the drive unit.

Abstract: A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid to the oral cavity of a user. The fluid reservoir includes a fluid port from which fluid is dispensed from the fluid reservoir, and through which the fluid reservoir is replenished. The fluid reservoir is moveable along the handle between a first position in which the fluid port is connected to the fluid delivery system, and a second position in which the fluid port is exposed to allow the fluid reservoir to be replenished.

Abstract: A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system. A motorised drive unit drives movement of a bristle carrier relative to the handle. At least part of an inlet conduit of the fluid delivery system lies adjacent to the external surface of the motor, and at least part of an outlet conduit of the fluid delivery system extends through the motor.

Abstract: A dental treatment appliance includes a handle, a nozzle for engaging the teeth of the user and for delivering a burst of working fluid to the teeth of a user, and a datum component also for engaging the teeth of the user. Each of the nozzle and the datum component is moveable relative to the handle. A control circuit detects relative movement between the nozzle and the datum component as the appliance is moved along the teeth of a user, and actuates the delivery of working fluid to the teeth of the user depending on the detected relative movement.
