Each of the liquid flow source and the gas flow source are coupled to a nozzle arrangement () arranged to be aimed at a subgingival region to be cleaned, the nozzle arrangement comprising at least one nozzle (). The system is configured to produce a fluid stream comprising a series of liquid pulses from said liquid flow source, said liquid pulses each having a duration of 5-100 ms, preferably 8-40 ms, with an interval of 1-50 ms, preferably 2-10 ms, between subsequent liquid pulses; and a gas flow from said gas flow source at least partially filling said intervals. Also disclosed is a nozzle arrangement for forming such a subgingival cleaning system.
