A powder jet device () for dispensing a dental material comprises a nozzle head () comprising a discharge nozzle. The powder jet device () further comprises a housing () comprising a valve portion (), which is connected to the nozzle head () and is adapted to receive a valve member (), and a chamber portion () comprising at least a first chamber () for storing a powder material. The chamber portion () comprises a proximal end () located adjacent the valve portion (), a distal end () located away from the valve portion () and a fluid channel () extending from the distal end () substantially to the proximal end () into the chamber. The powder jet device () further comprises a valve member () disposed within the valve portion (). The valve member () comprises a fluid supply passage () and is movable between a first position, in which a first fluid path () for delivery of a fluid from the fluid supply passage () into the chamber via the fluid channel () so as to create a dispersion from the powder material and a second fluid path () for delivery of the dispersion to the discharge nozzle are open, and a second position, in which at least the first fluid path () is closed.
