Abstract
A hand held motor driven dental prophylaxis device constructed primarily of plastic or other thin walled material is disclosed. The device includes a radially adjusting bearing circumscribing and supporting its drive shaft to minimize the imposition of side loads on the electric motor. The device also includes a switch which will operate reliably even if the apparatus is flexed or distorted.
