Abstract

Abstract The article of this disclosure is to be used to prevent injury to persons who may be subject to periodic or other types of seizures in which grinding of the teeth, of the jaws, and possible biting of the tongue such as may occur in epileptic seizures, electro-convulsive therapy, shock or related voluntary or involuntary action of the jaws so as to prevent injury resulting therefrom. The article of the invention includes a specifically designed block of material having certain characteristics of resistance to penetration of the teeth in conjunction with a handle arranged in the block so as to increase the resistance to biting through the same, all of the various elements being designed to prevent swallowing of the block, yet facilitate supplying the same by reason of the ability to maintain cleanliness and also to facilitate administration of suitable medication where desired since the jaws are not closed against such administration.
