ABSTRACT:
A dental saliva ejector has a perforated wall provided at each side of a suction opening to prevent tongue and muceous membranes of the patient to be sucked into the opening. The ejector further has a portion intended to rest against a front tooth of the mandible and a securing means intended to contact the chin such that the ejector is held in place by a clamping action between chain and front tooth to prevent pressure against the mouth bottom.
