I am 21 and never had braces when i was younger. I am regretting it now! I did some research and heard about invisalign so went to see a my local consultant and he said it was suitable for me. My father had agreed to pay for me to have the treatment as it quite expensive until he asked my usual dentist about it and he completely put him off. He said he didnt trust it. I am trying to convince my father otherwise but am starting to have doubts myself. I was wondering if you could give me some advice and your opinion on invisalign? thanks.
