An orthodontic bracket (10) includes a bracket body (12) having an archwire slot (16) configured to receive the archwire and a base surface (36) that at least in part defines the archwire slot. A movable member (14) is engaged with the bracket body and movable between an opened position and a closed position. A resilient member (20) is configured to engage the movable member (14) to impose a force that biases the movable member toward the base surface of the archwire slot. A method of moving a tooth includes inserting the archwire into the archwire slot, closing the movable member to capture the archwire within the archwire slot, and imposing a force on the movable member that biases the movable member toward the base surface of the archwire slot.
