Our DS got them when he was 10 1/2 and has had them just over two years now. Not sure when they are coming off....seems like never! Anyway, cost was about $4,800 (insurance paid one payment of $1,500). This was for everything, reatiner afterwards and everything. Did it in a couple of phases....top, then bottom and someday the reatiner when they are all out.
Question...did your regular dentist recommend the braces or did you take your child for a consult on your own? Most dentists I know wouldn't recommend braces unless it was a real need. I know my cousins DD had to have a lot of teeth pulled and got braces bercause of the crowding issue (actualy had another row of teeth behind the top teeth) but she was older than your child. Good luck!
