A single pair of pliers for bending orthodontic arch wires in all quadrants of a patients mouth. Includes first and second actuating members, each including a handle portion for grasping in the hand, and a head portion that projects at an angle. The actuating members are pivotally joined so that the head portions can be moved toward and away from each other into respective closed and open positions. A first occlusal jaw on head portion of the first actuating member has an internally angled channel profile and a second occlusal jaw on the head portion of the second actuating member also has an internally angled channel profile facing the other internal channel. A gingival jaw member having upper and lower externally angled corners is adapted to mate with the internally angled profiles of the upper and lower occlusal jaws, respectively, when the head portions are in the closed position.
