Experience with Bluegrass appliance

My son wore a palette expander which is different, but similar in that it went across the roof of the mouth. It took him about a week to get his speech and eating back to normal. Since taking pills wasn't part of his daily routine I don't recall how long that took to relearn. I'd give her at least a few days to adjust. Since the purpose of the bluegrass appliance is a substitute oral activity instead of thumb sucking I'd assume the dentist has it properly set where she can roll it with her tongue without too much mouth movement and too much pressure against her upper mouth area. I wouldn't compare it too precisely with another child's mouth placement.
