We took our 2 year old son to RPDO to have crowns placed. The treatment went well.
They estimated about $838 for the procedure. About a month after the procedure I received a bill for another $1500+. I called to dispute the large discrepancy from the estimate, and they told me that they were unable to predict what insurance would cover. They lowered the new bill by about $400, which still left over $1100 of an unexpected increase in what they billed us for.
