There is provided an assisting device for practicing lateral movement of a lower jaw to move a cheek-side cusp of a lower molar to a cheek-side surface of an upper molar. The assisting device includes an occlusion portion, which is placed in an oral cavity of a user and occluded by an upper central incisor and a lower central incisor, and a handle connected with the occlusion portion. The occlusion portion includes an upper tooth contact surface to be in contact with an incisal edge of the upper central incisor, and a lower tooth contact surface to be in contact with an incisal edge of the lower central incisor. The lower tooth contact surface has a flat surface. The occlusion portion provides a space between the incisal edge of the upper central incisor and the incisal edge of the lower central incisor. The upper tooth contact surface and the lower tooth contact surface cover entire movement ranges of the incisal edge of the upper central incisor and the incisal edge of the lower central incisor, respectively, when the lateral movement of the lower jaw is being practiced. It is, therefore, possible to provide an assisting device for practicing lateral movement of a lower jaw to assist a user to laterally move the lower jaw in a smooth manner.
