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.

An oral care device configured for placement in an oral cavity comprising:
- a base layer having a longitudinal axis;
- a power source disposed on a surface of the base layer, the power source being a polymer battery;
- and
- an electrode layer disposed on the surface of the base layer or on a surface of the power source, the electrode layer comprising a first electrode comprising a first metallic strip electrically connected to the power source and a second electrode comprising a second metallic strip electrically connected to the power source and substantially parallel to the first metallic strip, wherein the electrode layer is disposed such that a length of the first electrode and a length of the second electrode are substantially parallel to the longitudinal axis of the base layer.
