Self-ligating orthodontic brackets include a bracket base, at least one arch wire slot formed in the bracket base adapted to receive an arch wire therein, and a ligation cover which is selectively slidable relative to the bracket base between an open non-ligating position relative to the slot and a closed, ligating position relative to the slot. The exterior labial surface of both the base and ligation cover comprise a compound two axis curvature so that substantially all of the exterior labial surface of both the bracket base and the ligation cover present a smooth, continuous exterior surface that is substantially free of sharp discontinuities and crevices.
