Abstract: A dental saliva ejector tube and/or high volume evacuator tube guard having an annular ring segment for frictional and releasable attachment to the open, free end of the ejector tube or as an integral part of a suction tube, either flexible or rigid. The tube guard includes a pair of symmetrical guard loops lying in spaced, parallel planes each having two opposite ends which integrally extend from the annular ring segment and taper inwardly toward the central axis of the annular ring segment in a direction away from the ejector tube. In the preferred embodiment, the symmetrical guards have substantially straight segments extending between the distal end of the guards and the annular ring segment, forming an acute inner angle with the central axis of the ring segment.
