Claim:
1. A fluid droplet appliance for dental cleaning, comprising: a dental cleaning appliance having a body portion and a nozzle portion for exit of a spray of liquid droplets from a distal end thereof; a liquid reservoir wherein in operation liquid is moved from the reservoir into an area of the nozzle near an open proximal end thereof; a system for driving a plunger or piston element toward the proximal end of the nozzle with sufficient force that air acted on by the plunger or piston element is forced or released into the nozzle at a high rate of speed, sufficient to create a spray of liquid droplets when the moving air comes into contact with the liquid; and an orifice at a proximal end of the nozzle portion, through which air is forced by action of the plunger or piston element, wherein the system for moving a plunger or piston element includes a voice coil surrounding a magnet and a capacitor, wherein the magnet is connected to a piston member, and further including a source of power which charges the capacitor, wherein in operation the voice coil pulls the magnet to the rear of the appliance, away from the orifice, wherein discharge of the capacitor results in the magnet moving the plunger or piston member forwardly, forcing air through the orifice.
