A disposable saliva ejector with a single planar, double leaf shaped plate design embossed on the inner faces of the leaf plates with a series of arced ribs and then folded about its midpoint. A tab and slot arrangement joins the two plates when operationally folded. The arced ribs form a series of channels equidistant about the perimeter of the device. A trough runs along the linear axis of both of the plates to direct any fluid and debris that is sucked into the channels into a connected suction tube. Placement of the saliva ejector within the mouth lies along the interior of the patient's cheek, keeping the oral cavity clear of viewing obstructions.
