An orthodontic bracket assembly. The bracket assembly may generally include a base defining an archwire slot and having an occlusal portion and a gingival portion, a pivot member supported by the occlusal portion and defining a pivot axis, and a locking member supported by the pivot member for pivoting movement between an open position, in which the locking member permits access to the archwire slot, and a closed position, in which the locking member inhibits access to the archwire slot. The locking member may generally include a labial portion having a compressible gingival end engageable with the gingival portion of the base to retain the locking member in the closed position and an occlusal end, and a looped portion connected to the occlusal end of the labial portion, the looped portion extending below and then at least partially around the pivot member to support the locking member on the pivot member.
