The present invention relates to an orthodontic implement removably attached to a lip protector adapted to cover an orthodontic appliance for correction of irregular alignment of teeth having orthodontic brackets attached on the faces of teeth and orthodontic wires and ligature wires adapted to apply an orthodontic force to the teeth by their elastic forces, so as to reduce the likelihood of the occurrence of the harmful stimulus applied to the interior of lips, wherein the orthodontic implement includes an orthodontic tube removably attached to the lip protector so as to transmit an orthodontic force applied from the pushing force applied from the lips to the teeth and having locking protrusions formed at the upper and lower end portions of an opening formed on the rear side thereof, such that the pushing force applied from the lips or tongue is transmitted to the teeth, thereby accelerating the orthodontic force.
