Hi Emily! Welcome to the board
You know, it's funny...I had a bajillion questions before my first appointment too because I had these whole scenarios in my head of what I *thought* my treatment would or could be like. Then, after the appointment, I found that
none of my questions even applied because the ortho told me my treatment would be totally different from what I imagined. I worked myself up for nothing
Then, at the second appointment, when the molds and x-rays were in, it changed yet again. So, don't get yourself all worked up before you even know anything -- it'll drive you crazy, and probably be a waste of energy.
Also, the first appointment (at least for me) was really low-key. He basically just looked at my teeth and profile and my smile, took some measurements, and told me what he recommended. Remember that things change frequently in orthodontia, and you're not committed to anything at the first appointment.
Good luck and keep us posted!!
