My apologies, I stepped away for a while...
I'd shop around. Prices will vary, somewhat considerably too. Roughly, contingent on where you live, $4,000 to $6,000.
Additionally, if you go to a Dentist (who does Orthodontics/braces) as opposed to an Orthodontist, it may cost you less. If you live anywhere near a Dental School, you can get the Orthodontics for about 1/2 the price as well. And also, ALWAYS, once they've quoted you a price, ask about any further discounts... Military, good patient, "yes" good patient discounts. Discounts for cash paying, for paying monthly from your checking, etc.........!
What I'm saying is this: If you really want a service, the Dentist will also, almost always discount you additionally! But you'll need to ASK.
