The object of this invention is to obtain an electric battery which can be worn in the mouth of a person for its therapeutic effects, and also to give strength to the plate when false teeth are worn.
This battery consists of a non-conducting plate arranged to fit in the mouth, metal plates of opposite electric polarity imbedded in the non-conducting plate, conductors connecting the metal plates, such conductors imbedded in the non-conducting plate, and such metal plates so disposed as to be exposed to the action of an electric excitation by the saliva or other fluids in the mouth, and the organs of the mouth, to form elements completing the circuit of the battery.
We believe this to be the most rational form of electric treatment for cases which are indicated, inasmuch as we have a mild and uninterrupted current which may be made stronger or weaker to suit
