I recently learned about the risks of backflow (previous patients' blood/saliva etc.) that could rise up from the suction tube of a saliva ejector under certain circumstances. It seems not every dentist uses the valves that prevent this. Am I overreacting? My dentists have never stopped me from closing around the ejector tip which supposedly triggers the backflow. I have OCD and this has been a triggering discovery for me.
