Abstract: A method for removing an archwire from a slot of an orthodontic bracket having at least one retentive component involving creating a gap either between portions of a retentive component or between the retentive component and another component of the bracket and removing the archwire from the slot through the gap. The present invention is also directed to wire disengagement tools. Each tool includes a handle and a head portion which engages the retentive component. When the orthodontist applies a force, such as a rotational or plier-like motion, to the handle of the tool, the head portion exerts a force on the retentive portion to create a gap between portions of the retentive component or between the retentive component and another component of the orthodontic bracket. Each tool also includes a side arm, which lifts the archwire from the slot through the gap created by the head portion.
