I was referred to an orthodontist by my dentist to get braces, but I dont know what to expect walking through the orthodontist office. I do not have all the money to pay them up front but I want to get braces ASAP. I need to know what the overall cost would be for me if i only get braces on the top of my teeth done because the bottom is fine. I live i California and I'm 18. Do I need any money when I arrive for my appointment? how much?
