AbstractA dental appliance for use with an aspirator tube which forms part of a dental aspirating system, the system being used for periodically removing saliva/water from a patient's mouth by means of suction. The present improvement is a resilient foam sleeve that fits over the end of the aspirator tube which is inserted into the patient's mouth thereby providing a cushioning effect between the tube and the patient's mouth, a damping effect by reducing the rushing sound that usually accompanies such system, an enhanced suction efficiency between of the increased surface area available for suction and a filtering effect by preventing solid debris from entering the aspirator tube.
