I cannot get insurance for or afford the out of pocket charge of 3000.00-6000.00+ for invisalign or braces. I have what I call mild crowding.. have not made my appointment yet for the ortho.But I have called around I was quoted between 150.00-250.00. for a retainer for crowding. I also suffer from an underbite which hasn't caused me too many problems. Right now I just want to see if retainers will suffice to improve the crowding I do have. This condition keeps me from smiling :(
