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.

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 having electrodes thereon. In one aspect, the oral care implement may include a handle and a head, the head having a front surface and an opposite rear surface. A plurality of tooth cleaning elements may extend from the front surface of the head. A soft tissue cleaner may be located on the rear surface of the head, the soft tissue cleaner including a protuberance field. A first electrode and a second electrode are each operably coupled to a power source to have opposite electrical charges. The first and second electrodes may be spaced apart from one another and substantially surround the protuberance field. In other embodiments, the first and second electrodes may be embedded within or otherwise located within the protuberance field.

Abstract: An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece may comprise a lamp support structure comprising a lamp support surface; first and second lamps, each of the first and second lamps comprising a plurality of light emitters that generate light which is emitted from a rear surface of the lamp; each of the first and second lamps mounted to the lamp support surface, thereby forming a lamp assembly, each of the first and second lamps operably coupled to a control circuit having a power source; and a lamp retaining component coupled to the lamp support structure, a lower portion of the first lamp and an upper portion of the second lamp retained between the lamp retaining component and the lamp support surface of the lamp support structure.

Abstract: An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece comprises a lamp support structure comprising a lamp support surface and is formed of a first material. A flexible lamp is mounted to the lamp support surface so that a light emitting surface of the flexible lamp assumes a concave curvature, thereby forming a lamp assembly. A guard component is overmolded to the lamp assembly. The guard component is formed of an elastomeric material having a hardness that is less than a hardness of the first material. In one embodiment, the oral treatment device may be a teeth whitening device.
