ABSTRACT:
A saliva ejector is formed with a flattened body having an internal suction passage extending along the bottom and continuous to the top of the body. Suction apertures are provided in both the bottom and the top so that suction relief is provided at the top of the ejector, even though lower apertures are blocked by soft tissue. The body of the ejector is made of two mating plates that are snapped together and clamp over the end of a vacuum tube to be connected to the ejector. The extent of the flattened body above its bottom portion permits it to act as a tongue guard, separating the tongue from the teeth, and facilitates location of the vacuum relief ports. A chin holder, having an integral side opening clamp is readily clamped on the vacuum tube to securely position the ejector within the oral cavity.
