An oral care implement having conductive protrusions. In one embodiment, the oral care implement includes a handle and a head coupled to the handle. Furthermore, the oral care implement includes a power source. A plurality of conductive protrusions may be electrically coupled to the power source. The plurality of conductive protrusions may include a base proximate the head and a distal end spaced from the head. Furthermore, at least one of the conductive protrusions may taper from the base to the distal end.

An oral appliance for use with a subject in his/her mouth includes a flexible tube having an input end and an output end and an electrode coupled to the flexible tube adjacent the output end. The flexible tube is adapted to be positioned in the subject's oral cavity with the output end positioned in a posterior region of the oral cavity. The electrode is adapted and configured to administer an electrical stimulation to the posterior region of the oral cavity. An electrode lead is disposed within the flexible tube and connected to the electrode. An electrical stimulation control unit is connected to the electrode lead. A method of administering an electrical stimulation to a posterior region of an oral cavity of a subject is also provided.

In some embodiments, an oral care implement includes a housing, a power source, and a plurality of conductive protrusions extending from a surface of the housing. Also disclosed are methods of using the oral care implement, for example, for treating conditions in the oral cavity.
