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 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 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: 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 care implement having electrodes thereon. In one aspect, the oral care implement may include a handle and a head, the head having an outer surface. A plurality of tooth cleaning elements extend from the head. At least one oral care agent dispenser is located on the head. A first electrode and a second electrode are located on the head and operably coupled to a power source to have opposite electrical charges. In some embodiments at least one of the first and second electrodes may be a sacrificial electrode. The oral care agent dispenser may be an outlet that is coupled to an oral care fluid in a reservoir and/or a solid release polymer that releases an oral care agent over time during use of the oral care implement.
