A disposable, plastic dental implement is provided for enabling both the aspiration of fluids from a patient's mouth and the retracting of soft tissues in the patient's mouth. The implement is a slender, elongate member having a hollow tubular portion having a suction end and a connection end for connecting the member to a conventional suction tube. Relatively narrow, first and second, longitudinally-extending fins project sidewardly from opposite, lower, side regions of said tubular portion. These fins, which are substantially uniform in width and thickness, extend around a suction end of the tubular member to abut one another. A region of the fins around the suction end of tubular portion are curved downwardly to form an arcuate, tissue-retraction tip at the suction end of the member. Preferably, the width of the fins is less than the outside diameter of the tubular portion at its connection end. The suction end of the tubular portion is cut at a slant and has at least two opposing recesses which enable suction to be broken between the member and soft tissues of the patient's mouth should the need arise.
