A wire bending apparatus for bending an arch wire or the like at its opposing ends and toward the teeth of the user, so as to isolate the loose end and thereby prevent discomfort. The preferred embodiment of the present invention contemplates a device wherein there is provided an elongated body having first and second ends, a pivot piece having a cam associated therewith at the first end, a handle for applying a pushing or pulling force associated with the second end, the handle configured to move along the length of the body, and a drive member running from the handle to the cam, so as to impart linear pressure from the handle to the cam, thereby providing rotational movement at the pivot piece. The handle may be biased via spring or the like, as desired. In use, the end of the arch wire is inserted into a lateral bore formed in the pivot piece, and the handle urged in a direction along the length of the body to impart linear motion to the cam, which converts the linear motion to circular or rotational motion at the pivot piece, the pivot piece engaging and bending the arch wire so that its free end is situated adjacent to the patient's teeth, isolating same. An alternative embodiment contemplates a pliers-like handle configuration wherein the handles may be squeezed toward one another to actuate the pivot piece and bend the arch wire or the like.
