A dental accessory device having a pivot member hingedly attached to a base member and a central opening between the two for receiving a sponge. A latch and corresponding groove or detent hold the pivot member to the base member and one or more teeth-like projections on the inner surface of each member secure the sponge in place. An elongate stem protruding from the bottom of the base member is insertable into an external dental instrument. A dental bur component with hinged cover and a ruler on the top of the device provides easy access to a variety of dental burs and aids in assessing the depth of a root canal being performed, respectively. Attached to the side of the device is a well for holding dental lubricants necessary to the endodontic procedure.
