The utility model provides a jaw-pad movable appliance for controlling root to move in lip-direction. The appliance comprises a pivot wire and a correcting archwire, wherein the pivot wire is fixed on the tongue side of a correcting tooth; the middle part of the pivot wire forms an arc shape, so as to be attached with the near-gum part on the tongue side of the dental crown of the correcting tooth, and the two sides of the wire form a ring so as to facilitate adjusting; the correcting archwire forms correcting stress in the palatoglossal direction in order to drive the dental crown to move in the palatoglossal direction, and a tooth root to move in the lip direction; the correcting archwire is made of a flexible archwire. The appliance eliminates the bending of a fixed correcting archwire, facilitates adjusting and cleaning, and efficiently and softly control the root; the pivot wire is adopted to be propped against the near-gum part on the tongue side of the dental crown as a pivot of a lever; when the stress in the palatoglossal direction is generated by the correcting archwire fixed at the cutting end of the dental crown, the tooth root is driven to move in the lip direction, so as to gradually complete the correction of a malposed tooth root in the palatoglossal direction.
