Crowding and crooked teeth is just that.  Nothing to do with a bite.  It may make the bite more unstable if crowding continues.   Moving teeth with braces or retainers can fix crooked teeth and a static bite, but cannot necessarily change a dynamic bite.  You want  braces and retainers to also change a dynamic bite!!!  If a dynamic bite is caused by a skeleton imbalance, if may not be able to be  corrected unless some sort of surgery is performed.  Patients should be aware that correcting crooked teeth without fixing a dynamic bite is just that.
