ABSTRACT:
A jaw retention device operative for use by a dental patient to urge the patient's lower jaw into an open position thereby relieving stress on the jaw muscles during dental procedures. The device includes a hand held object connected by an elongated flexible member to a mouth piece. The mouth piece is preferably constructed of a plastic material having sufficient flexibility to permit the mouth piece to bend and release from the lower teeth when the flexible member is subjected to a selected threshold tension.
