ABSTRACT:
A dental instrument for preparing a tooth for receiving a crown in an area not visible to the dentist which includes a guide member disposed adjacent to the cutting instrument and is freely rotatable relative to the cutting instrument. The guide surrounds the cutting instrument and includes at its lower end a shield that prevents the cutting instrument from contacting the surrounding gum. The guide limits the horizontal depth of cut and vertical depth of cut into the tooth during the tooth preparation.
