Abstract: A pneumatic dental care device for in-home use that is particularly suited for cleaning and providing prophylaxis of teeth, gingiva, and other oral tissue wherein pressurized air is directed into a user's oral cavity to clean teeth, remove oral debris and to both stimulate and massage gum line tissue. The compressed air, by means of a length of flexible tube, is delivered from a pressurized air source to a hand piece having both a nozzle tip and only one hand piece conduit. A control button disposed on the hand piece operably opens and closes a valve located within the hand piece, thereby allowing or stopping the outflow of compressed air from the nozzle tip of the hand piece. Additionally, a method of installing such a pneumatic dental care device for in-home use is disclosed.
