Hi Alicia,
In the US band surgery can run from $15,000 to $20,000 depending on the doctor. Fills can also run from $100 to $200 each adjustment. In Mexico the fees are from $8,500 to $12,000 with some doctors offering free fills for life, BUT you would have to pay your own way to get there and pay for the x-ray room in the hospital when they do the fill.
