ABSTRACT:
For use with an oral irrigating appliance which provides a series of pulses of fluid through a flexible hose to a user-held handle, a subgingival delivery tip is in the form of an elongated hollow shank with a knob at one end thereof. Formed at the other end of the shank is an in-turned constriction which defines a passage more narrow than the inner width of the shank. A probe of resilient material has an outer cone-shaped portion projecting away from and with its base seated adjacent to the outer end of the constriction. That probe also has a necked-down central portion continuing centrally from its base through the passage and continuing into an enlarged button-shaped inner portion on the inner end of that central portion with that inner portion being received within the shank in a position seated adjacent to the innermost end of the passage. A channel is pierced centrally through the entirety of all of the different portions of the probe.
