My dd had major issues with her teeth. She had a space matainer since she was about 6...there's so much crowding in her mouth that there was no room for teeth. She had to have a couple of teeth pulled before getting her braces on (this was done by her dentist...which is covered under insurance...the ortho isn't).
She had her braces on for almost 2 years. Within weeks you could start to see a difference! Her braces cost me $4650 ($1000 down and $175/mo). Her care was excellent. If she needs the braces, look around and get some estimates, but don't wait too long. A year earlier when I asked about braces for my dd, I was quoted about $3000. It goes up a lot each year!
About a month after her braces came off, my dd had to have her wisdom teeth out! Her final x-ray showed that her wisdom teeth were coming in crooked. After paying out almost $5000, I wasn't going to let them be moved around by the wisdom teeth!!! So, I had to search to find a surgeon who accepted MA....otherwise it was going to cost another $2000 to have the wisdom teeth out!
