this is a metal bar that goes across the roof of your mouth.. It is held in place by two brackets on your back teeth..For the first 15-30 days you have to place a little key in the expander and turn it.. The expander makes the roof of your mouth wider.. The expander is usually kept in place for about 1 year..Health Question & Answer
