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.
