Abstract

This invention relates to tongue deflectors which attach to saliva ejectors. The tongue deflector of this invention is formed of a flattened body with sufficient height to extend from the floor of the mouth to the top of tooth surfaces, so that the body may extend along the inner sides of the teeth to separate contact between the tongue and at least some of the teeth. A plurality of slotted cuts are provided through the body of the device to form a plurality of straps which may be pulled or pushed away from the body. The saliva ejector stem is passed through the strap so the saliva ejector tip nests in the tongue deflector body, and the tongue deflector attaches to the saliva ejector tip.
