Abstract
A device for sharpening dental instruments is disclosed. The device is particularly advantageous for sharpening and shaping dental curettes and universals. The device is comprised of a generally rectangular and elongate wedge-shaped ceramic stone. The stone has a planar front surface and a planar back surface, the surfaces are obliquely positioned with respect to each other. A rounded top lip and a rounded bottom lip join the front surface and the back surface. The top surface has a groove, semicircular in cross-section, extending lengthwise. The groove is sized to receive the toe portion of dental curettes or universals for sharpening and shaping.
