The invention relates to a lingual bracket, which comprises a bracket body and a movable wing. The lingual bracket is characterized in that: the bracket body consists of a bracket base and a fixed wing integrated with the bracket base, wherein the lower surface of the bracket base is provided with anti-skidding threads; the fixed wing is convexly arranged at one end of the bracket base; a throughhole is formed on a central axis of the fixed wing; one end of a movable wing is provided with an arch wire hook and the other end of the movable wing is provided with a fixed part; the fixed part ofthe movable wing passes through the through hole of the fixed wing; a spring is sleeved on the section; and one end of the spring presses against the fixed wing; and the other end of the spring is positioned on the fixed part of the movable wing. The arch wire hook of the movable wing can hook an arch wire, and generates a continuous correction force by means of the spring, so that teeth are corrected according to the expected moulding of the arch wire.
