My 8 yo DD has a pretty small jaw and some crowded teeth. She has lost maybe 6-8 baby teeth now and has a few of the permanent teeth coming in and there's not a heck of a lot of room there. So the dentist referred us to an orthodontist to see if there's anything preventative we could do at this point. So we went to the orthodontist who is now recommending this retainer like appliance to expand her jaw. It has sort of a spring there and they said you turn it once a week to expand it and they wear it for about 6 months. The cost is about $2900 and our insurance doesn't cover it. He is saying if we do this now then there'll be more room for the incoming teeth and then when she does get braces once all her permanent teeth are in they won't need to stay on as long. This all sounds a little hokey to me. Anyone have experience with this?
