Orthodontic brackets include a bracket base, at least one arch wire slot formed in the base adapted to receive an arch wire therein, and a moveable structure for selectively narrowing the width of at least a portion of the arch wire slot so as to allow for engagement of an undersized arch wire having a width less than the slot width. The moveable structure for selectively narrowing the width of the arch wire slot may be defined by one or more spaced apart cuts disposed in at least one side wall defining the arch wire slot so as to define a bendable portion of the sidewall.
