1. An oral care implement comprising:
a housing comprising a reservoir storing an oral care fluid and a dispensing conduit terminating in a discharge opening, the dispensing conduit fluidly coupled to the reservoir for delivering the oral care fluid from the reservoir to the discharge opening;
a power source;
a first electrode operably coupled to the power source, the first electrode located within the reservoir of the housing and being electrically coupled to the oral care fluid located in the reservoir;
a second electrode operably coupled to the power source, the second electrode located within the dispensing conduit of the housing and being electrically coupled to the oral care fluid as the oral care fluid passes through the dispensing conduit towards the discharge opening; and
an actuator operably coupled to an electrical circuit and configured to energize the first and second electrodes upon being actuated, thereby generating an electrical charge at the second electrode to which the oral care fluid in the dispensing conduit is exposed prior to being discharged through the discharge opening.
