PROBLEM TO BE SOLVED: To provide an expected effect in a dentition correcting mouthpiece for accelerating dentition correction by applying vibrations generated by an excitation actuator to the dentition of a user wearing the mouthpiece. SOLUTION: An upper side piece 72 and a lower side piece 71 respectively corresponding to upper and lower dentitions are used in a pair, the excitation actuator 8 is stored in at least one of them, the upper side piece 72 and the lower side piece 71 are connected by connection members 21 and 22 and integrated, and positions for providing the connection members 21 and 22 are separated from a correction object tooth. Thus, an occlusion state (occlusal force and occlusal surface) at the position of the excitation actuator 8 is held fixed and a user is prevented from unconsciously biting to change the way of the transmission of the vibrations. Thus, expected vibrations are continuously applied to the correction object tooth without putting the burden of keeping an open mouth state on the user and the expected effect is obtained.
