ABSTRACT:
The invention is directed to a jet nozzle (1) for a handpiece of an oral irrigator, which has a nozzle head (2) in which a feed line (4) runs. The feed line (4) opens into an outlet orifice (5) from which a liquid can emerge in the form of a single jet. A constriction (6) is provided in the feed line (4). The constriction (6) acts to produce a large number of microfine gas bubbles. The microfine gas bubbles are better suited to penetrate deep into subcrestal pockets in order to kill anaerobic bacteria which have settled there by the supply of oxygen, hence treating and curing inflammations of the gums.
