Abstract: An anatomically correct tongue scraping tool has a blade holder mounted at one end of an elongated handle and a replaceable blade selectively and rigidly engaged within the blade holder. A scraping portion of the blade extends outwardly from the blade holder and terminates with a smoothly integrated curvilinear edge having curve segments including: two spaced apart, concave segments, a convex segment, and two spaced apart, approximately circular segments which join the curvilinear edge with sides of the blade, wherein, the convex segment separates the concave segments and is positioned medially on the curvilinear edge.

Abstract: A dental appliance apparatus is made up of a bite block and a snap-in, positionable fluid ejector. An aspirator tube is positioned and slideably engaged within a tube holder which, in turn, is rotatably engaged with the bite block. This allows for selective angular positioning of the aspirator tube so as to accommodate a wide range of patients in aspirating fluids as efficiently as possible.
