Um.. Try like $5000 to $7000. It all depends on if you need your jaw broken or not and what kind of braces you want. Sometimes when your older(19-up) you need your jaw broken because it has set in an imperfect way and teeth cannot be properly fixed. And insurance(at least in Canada) is 50% if you have it. If your married or have parents who both have insurance then it might be fully covered. Again this is Canadian facts because that's all i know.
I hope i helped, at least a little bit.
About $70 dollars
