Abstract: A fluid delivery system for a dental cleaning appliance includes a nozzle for delivering a burst of working fluid to the teeth of a user, and a fluid conduit for conveying working fluid to the nozzle. A body of the nozzle defines a fluid chamber and a channel for conveying working fluid from the fluid chamber to a fluid outlet from the nozzle. The fluid chamber has a tangential inlet for receiving working fluid from the fluid conduit.
