Abstract A dental aspirator tube comprises a tubular handle having a tip at one end for insertion into a patient's mouth and which is adapted to be connected at its other end via a length of flexible tubing to suction equipment. The tip is formed by a bent tube which is securely fixed to the tubular handle. The flexible tubing is detachably connected to the handle via a tapered or graduated connector section. The tip handle and connector are preferably formed as an integral plastics structure.
