Hi everyone - THANK you all so much for responding!

That really helped a lot!
Actually - the ortho mentioned taking a look at my roots and I had never heard of this before - that you can also straighten the root. So I'm glad to see your replies about the position of the roots - I was going to ask about this on the forum too.
As for paying - I don't know if it's included. I guess I will find out next time I go to the appt. But I'm glad to read it's common to have xrays.
I hope I don't have to reposition any brackets though! I really can't handle that tongue/cheek guard thing.
Thanks for your time and support!
