Air Polishing is a technique which uses water and air pressure of precisely processed powders manufactured in a slurry via handpiece nozzle. Compressed air in a warm spray propels the fine particles and directs them to the exteriors of the teeth. This pressurized air, powder, water removes plaques, soft deposits like food particles trapped inside teeth, surface stains. An air polisher gives a substitute method for removing hard stains which are deposited on the teeth.
