A triple wing orthodontic bracket, bracket cover, and method of use is di sclosed. The bracket has a slot liner for reducing friction between an archw ire and the bracket, wherein the liner is flared at its ends. The bracket co ver has: a rod-shaped hinge for rotating in recesses between a bracket base, and bracket wings on one of a gingival and occlusal bracket side, a slot co ver, and a cross member for rotating the slot cover between covering a brack et archwire slot, and uncovering the slot, wherein the rotation pivots the h inge in the recesses. The hinge and recesses frictionally engage one another , wherein in a first position, the hinge attaches and detaches from the brac ket, and after pivoting the hinge to another position in the recesses, the h inge is secured therein. Interaction between the hinge and the recesses may cause the slot cover to move to cover the slot.
