An absorbent core is contained within a generally wedge shaped shell. The core is constructed of cotton or other known absorbent material. The shell is constructed of a material which is rigid enough to hold a mouth of a patient in an open position when the bite block is inserted within the mouth, for example, foamed polystyrene. The shell has a first side and a second side, which are generally triangular shaped and opposite each other. The shell further includes a third side and a fourth side, which are generally rectangular, and which each span between the first and second sides of the shell. Each of the third and fourth sides include alternating peaks and valleys, for providing a gripping surface for the teeth of the patient. The first and second sides each contain an elongated side aperture therein. The core spans completely between the first and second sides at the side apertures. An end aperture is provided at the apex of the shell. The core spans completely to the end aperture.
