Abstract
The appliance (, FIG.) includes a body portion () and a nozzle portion () through which a spray of liquid droplets exits from a distal end thereof for cleaning of dental regions. The nozzle includes an orifice () at a proximal end thereof adjacent the body portion, as well as a pump () for moving liquid into an area of the nozzle just forward of the orifice. A mechanical system () is provided for moving a plunger or piston element () first away from the orifice under tension, such as a compression spring (), and then controllably releasing the plunger or piston toward the orifice, the plunger/piston moving with sufficient force that atmospheric air which has been drawn into the appliance between the plunger or piston is forced through the orifice at a sufficiently high rate of speed to produce a spray of fluid droplets for dental cleaning when the moving air comes into contact with the liquid in the nozzle.
