Abstract
The present invention provides a dental grinding tool which is unlikely to damage gums and capable of finely shaping a formation part on which a crown is placed, and further provides a method for making the same. The dental grinding tool is made by forming a chamferred part on the end portion of a columnar metal base, and fixing abrasive grainsonto the end faceof the metal base, wherein all of the abrasive grainsexist inside the outer circumferential lineof the end faceof the metal base. Grinding is performed only by the end face. When a boundary part between teeth and gums is ground, only a chamferred partwhich have no abrasive grains comes in contact with the gums. Therefore, the damage to the gums is prevented.
