An instrument for debonding an orthodontic bracket from a tooth surface includes first and second plier portions coupled for relative pivotal movement. A lever arm pivotally movable relative to the first and second plier portions has a tooth engaging member on a first end. In one embodiment, the tooth engaging member is positioned on the lever arm for movement between a jaw of the plier portions and the tooth surface when a second end of the lever arm is pivotally manipulated in a direction toward a handle of the plier portions. In another embodiment, at least part of at least one plier portion is flexible relative to the lever arm such that the lever arm moves the tooth engaging member relative to a jaw of the plier portions after the bracket engaging portions are engaged with the orthodontic bracket and the handles and lever arm pivotally manipulated toward one another.
