Abstract: One object of the present invention is to provide a saliva ejector tip (3) having holes (6) on a recessed flat surface (4) for providing additional hole area than is available in conventional ejector tips, and away from the soft tissue, where they can cause injurious sucking.The other object is to provide a saliva ejector capable of self controlling the total area of holes by using the strength of the internal vacuum to displace a movable portion (17) of the tip, so that holes (12) and (13) are aligned for increasing the total hole area. Such an increase expedites the rate of removal of fluids so that subsequent inflow of air reduces the vacuum strength, and thereby, helps releasing the soft tissue that may have been sucked up by other holes. Upon lowering of the internal vacuum, the movable portion of the tip returns to its normal position.
