Abstract: A toothbrush includes a handle, a head at a distal end of the handle comprising a bristle plate, a hole extending through the bristle plate, a plurality of bristles at least partially disposed in the hole and extending from the hole in a direction away from the head, and a reservoir in fluid communication with the hole. Fluid in the reservoir enters the tuft holes and is wicked out of the head of the toothbrushes by capillaries formed between the bristles.

Abstract: An oral care implement includes a housing defining a cavity and configured for at least partial insertion into an oral cavity. An opening in the housing fluidly connects the cavity to an environment of the housing. First and second spaced electrodes are disposed in the cavity. An electrical connection electrically connects the first electrode and the second electrode to a power source. At least one of the first electrode or the second electrode is a sacrificial electrode and passing a current through the electrical connection causes the sacrificial electrode to oxidize.
