A pliant elastomeric unitary sleeve is adapted to removably fit the elongate shank of a dental tool which extends beyond a longitudinal end of the shank, whereby to ergonomically enhance a finger grip of the shank in operative manipulation of the dental tool for a dental procedure, said sleeve being characterized by an axially extending generally cylindrical bore sized for circumferentially stressed resilient engagement to said shank, said sleeve being further characterized by an exterior profile, wherein a first peripherally continuous enlargement near one longitudinal end and a second peripherally continuous enlargement near the opposite longitudinal end are longitudinally spaced by a circumferential concavity which is an arcuate contour of revolution about the axis of the sleeve.
