A backflow-prevention system that substantially prevents contaminant backflow at a treatment site. The system includes a fluid ejector tube for insertion into the patient's mouth and a backflow prevention device that receives fluid from the fluid ejector tube. The backflow prevention device includes an internally positioned valve member. The valve member limits contaminant backflow. The valve member is movable between open and closed positions based on a vacuum pressure condition in the system.
