Provided is an orthodontic buccal tube, which is capable of preventing glue from flowing out towards a boundary between a tooth (300) and a base (100), being firmly attached to a face of the tooth (300), and being easily removed from the face of the tooth (300) after being used. The orthodontic buccal tube is attached to the face of the tooth (300) by the glue (400), and includes a base (100) having a bonding face (110) on one side of the buccal tube, a body (200) having a slot (210) into which an archwire is inserted in the middle of the body (200) on a side opposite the base, and a glue anti-outflow step (120) formed along an outer circumference of the bonding face (110) at a predetermined height in a closed loop. The glue anti-outflow step (120) prevents the glue (400) applied to the bonding face (110) from flowing out towards a boundary between the base (100) and the tooth (300).
