We tried Invisalign with a different orthodontist for over a year and it was a total waste of time.
We had a few prior consultations with mainstream orthodontists when he was younger telling us they'd have to pull teeth and he would need an expander. His father wasn't willing to do all of that so it was a no go.
The bottom line is that we've had several consultations over the years, and have already contracted with and paid this orthodontist, who is highly respected and works with the city's children's hospital on the hard cases. I doubt we'd find better anywhere in this city. I'm just frustrated with this process that isn't going well, my son's pain, the waste of time, the huge investment I made and now I fear it might not work. That's why I partly wish I could just get a refund, take the braces off and forget the whole thing.
