I had metal braces as a teen, along with: headgear (that I didn't wear enough) to move my top jaw forward and an expander on my top jaw. My lower jaw was never treated.
My orthodontist at the time refused to do anything and insisted on doing orthognathic surgery. I'm still not sure about orthognathic surgery, since my insurance provider will not cover it and it would wipe out my saving or leave me with debt.
Can Invisalign be used to help pull my upper jaw forward to the point where I would have a functional bite?
