have found that it is much easier and safer for untrained persons to guide a polishing device through the palm of the hand than it is for them to guide a polishing device which is held in the fingers alone the central shaft location also provides another feature of my invention which is that untrained users of the device cannot easily get access to those areas of the mouth where tartar tends to form people using the device will of course be looking into a mirror as they guide the tip and will thus not be able to see around the housing of the device to get at those areas requiring professional care safety is also enhanced by the knowledge of the general public deriving from their experiences in dental offices that applying excessive pressure may cause pain it must be remembered that my invention is not a professional dental appliance and is intended for cosmetic cleaning only the foregoing description of the invention has been directed to a particular embodiment in accordance with the requirements of the patent act and for purposes of explanation and illustration it will be apparent however to those skilled in the art that many modifications and changes may be made without departing from the scope and spirit.
