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.

An oral care implement having electrodes thereon. In one aspect, the oral care implement may include a handle and a head, the head having an exposed outer surface. A first depression is formed in the exposed outer surface of the head. A first sacrificial electrode is disposed within the first depression and has an exposed surface that is recessed relative to the exposed outer surface of the head. A second electrode is located on the head. Each of the first and second electrodes is operably coupled to a power source to have opposite electrical charges.

The disclosure provides an ionic toothbrush having an elongated body that may be configured to have a one-piece design, or alternatively one or more components of the ionic toothbrush may be removable and/or replaceable. In some embodiments, the present disclosure provides an ionic toothbrush which includes a handle portion, a brush head portion including a plurality of bristle tufts; and an electrical circuit configured to transmit a negative electrical charge through at least a portion of the brush head, wherein the electrical circuit includes one or more sections of conductive resin present on an outer surface of one or both of the handle portion and the brush head portion.

An oral care device may include: a body including a head; a plurality of teeth cleaning elements extending from the head; a first sacrificial electrode on the head; a second sacrificial electrode on the head and spaced apart from the first sacrificial electrode; a power source; and a controller configured to alternate between an ON state and an OFF state, wherein: in the ON state the controller operably couples the power source to the first and second sacrificial electrodes to create an electric potential between the first sacrificial electrode and the second sacrificial electrode, the electric potential having one of a first polarity and a second polarity, and for each successive transition from the OFF state to the ON state, the controller is configured to alternate between the first polarity and the second polarity.

An oral care device may include: a body including a head; a plurality of teeth cleaning elements extending from the head; a first electrode on the head; a second electrode on the head and spaced apart from the first electrode, wherein at least one of the first and second electrodes is a sacrificial electrode; a power source; and a controller configured to operably couple the power source to the first and second electrodes to create an electric potential between the first and second electrodes so that ions are released from the sacrificial electrode during a brushing session; wherein the controller is configured to change a magnitude of the electric potential the brushing session ends.

A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

A container, a toothbrush, or a device including at least one sacrificial electrode. In one aspect, the container may include a body adapted to contain an oral care solution and a cap selectively removable from the body. The cap may include a cavity configured to contain a fluid, a first electrode comprising a sacrificial metal, a second electrode spaced from the first electrode, and an electrical connection electrically connecting the first electrode and the second electrode to a power source. Activation of the power source may generate an electric field between the first and second electrodes, thereby causing the sacrificial metal of the first electrode to release ions into the fluid in the cavity of the cap.

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.
