Hi, I'm 24 and had metal fixed braces when I was 12 years old. My teeth have moved and I have a 7mm overjet. I have visited an orthodontist for consultation. I was sent a treatment plan for full invisalign and interproximal reduction. l asked how much my overjet would be reduced by. I want a normal bite so my teeth don't stick into my lower lip. They have now revised my treatment plan which will most likely involve Temporary Anchorage Devices and extractions which is much more complex! Help, any advice?
