First, Happy Birthday, Michele!!!
Next, ummm, I didn't know your teeth move back after braces if you don't wear a retainer. Is that for the rest of your life? My kid is getting braces, she went to the orthodontist yesterday. She's getting the good ol' railroad tracks, not the Invisalign.
But now I thinking this is major scam. Braces that cost a fortune and THEN you still have to wear a retainer?
And when you say it hurts--how much? A teenager is already a handful--a screaming, moaning, complaining one does not sound like a good four years ahead.
