1. An oral irrigator comprising:
- a fluid reservoir;
a pump in fluid communication with the fluid reservoir;
a handle in fluid communication with the pump;
a jet tip in fluid communication with the handle, wherein the jet tip includes a fluid conduit therein and the fluid conduit has a proximal end adjacent to the handle and an opposite distal end terminating at a nozzle aperture configured to expel a stream of fluid onto a surface inside an oral cavity;
a radiant energy source disposed within the distal end of the fluid conduit and upstream of the nozzle aperture; and
a fluid pocket defined within the fluid conduit at least partially between the radiant energy source and the nozzle aperture, wherein the radiant energy source is in fluid communication with the fluid pocket.

Abstract
An oral irrigator includes a base having a pump mechanism, a reservoir housed within the base and fluidically connected with the pump mechanism. A handle with a jet tip is connected with an outlet from the pump mechanism to receive a pressurized fluid stream from the reservoir to direct a fluid at a surface inside an oral cavity. The oral irrigator also includes a radiant energy source and delivery system for directing radiant energy at a surface inside an oral cavity.

8. An oral irrigator comprising:
-
a pump mechanism; a reservoir in fluid communication with the pump mechanism; a jet tip in fluid communication with the pump mechanism and including a fluid conduit with a distal end terminating at a narrowing nozzle aperture, wherein the jet tip is configured to direct fluid pumped from the reservoir by the pump mechanism through the nozzle aperture as a fluid stream at a surface inside an oral cavity; a laser diode housed within the distal end of the fluid conduit upstream of the nozzle aperture and configured to generate a coherent stream of radiant energy at a surface inside the oral cavity; and a fluid pocket defined within the fluid conduit at least partially between the laser diode and the nozzle aperture, wherein the laser diode is in fluid communication with the fluid pocket. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
