The present invention relates to a dental suction device for managing fluid in a patient's mouth during a dental procedure. The dental suction device comprises a pliable tube having a first end for connection to a vacuum source and a second end that can be looped to form a suction end for positioning in a patient's mouth. The loop is adjustably secured by a pair of retaining collars positioned a certain distance apart from each other along the second end of the tube and connected together by a tie. The loop, adjusted to accommodate the shape of the patient's mouth, is secured around the terminal end of a row of teeth in the patient's mouth. In this way, the dental suction device can be maintained and operated in the patient's mouth during a dental procedure.
