The feeling that the teeth have got used to the appliance being tightened comes quickly – in some children even within a day of turning the screw. Even so, moving the teeth through the bone takes a certain amount of time, so if the appliance is turned more often than recommended, one of two things happens: either the appliance stops fitting the teeth and ‘drops’, or you turn the screw and the pressure from the teeth pushes it back, so you are making ‘empty’ turns that achieve nothing and don't move the treatment forward.
