The present invention provides a gas dental abrasive system using pressurized helium gas. The system includes an apparatus for abrading teeth using an abradant having a pressurized helium gas source and a control for regulating pressurized helium gas to form a carrier gas containing helium gas for carrying the abradant to teeth. The system also includes a dual gas apparatus with a pressurized helium gas source; a source of pressurized non-helium gas; and a control capable of selectively mixing the pressurized helium and the pressurized non-helium gas to form a carrier gas for carrying the abradant to teeth, wherein the carrier gas can contain from 0-100% helium gas. The system further includes a method of abrading teeth with the steps of providing an abradant; and delivering the abradant to teeth with pressurized helium carrier gas.
