Abstract
A nozzle (12) for an oral irrigator device (10) having a guidance tip (34) with at least one orifice (36) at one end, and a nozzle spacer assembly (58) positioned around the at least one orifice (36). The at least one orifice is configured to expel a fluid as one of a jet, a spray, or any combination thereof. The nozzle spacer assembly (58) comprises at least two pairs of pliable spacers (60) that extend from the surface (35) for ensuring that the area at an entrance of an interproximal space between two teeth are treated, and (ii) establishing an improved angle of impact of the fluid expelled from the orifice.
