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.

Abstract: An oral care implement having electrodes thereon. In one aspect, the oral care implement may include a handle and a head, the head having a transverse through hole defined by an upper surface and a lower surface. A first electrode and a second electrode are located on the head and operably coupled to a power source to have opposite electrical charges. At least one of the first and second electrodes may be located on one of the upper and lower surfaces of the transverse through hole. In some embodiments, the first electrode is located on the upper surface of the transverse through hole and the second electrode is located on the lower surface of the transverse through hole.

Abstract: 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.

Abstract: 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.
