An improved dental apparatus for removing excess saliva during dental procedures and also for maintaining a patient's jaw comfortably in an open position. A dental bite block has occlusal resting portions joined by an arcuate anterior member. One occlusal resting portion has a main vacuum port extending angularly therefrom and communicating with a hollow channel having openings on opposing lateral surfaces of said occlusal resting portion. The main vacuum port operably receives the suction hose of a vacuum evacuation system. Lingual and buccal saliva ejector ports, each having circumferential grooved attachments and nozzle portions, are communicably connected to either opening on the occlusal resting portion. Saliva is communicated from the ejector ports into the main port, whereupon it is communicated into the vacuum system for dispensation.
