I am sorry to hear that, it would have been ideal for you to have your fills close to home.
I am not surprised though, here in Canada, the same thing happens, my clinic in Mississauga has been getting calls from TJ patients and because my clinic did not perform the surgery, they won't do the fills.
I assumed the procedure was the same whereever you go, but that may not always be the case. At the OCC the surgery is much shorter than here in Canada. My surgery took almost 2 hours and I heard some of the surgeries done at OCC are 20-40 minutes tops.
I wish you luck finding a fill centre close by.
Take care, Cathy
