billing was a nightmare! my husband needed a filling and asked the office how much it would cost because we didn't have much money and needed to budget it. they said anywhere between $70 and $300! they filled the tooth (minor and without pain meds or nitrus oxide) and billed around $250! our insurance said "reasonable and customary rates" were $175. The office then billed US the difference! I sent a reply that we had expressed concern about the costs, it seemed steep for such a small filling and would they please accept our insurance's view that $175 was reasonable (they were paid that from our insurance). they did not respond except for another bill for the difference. We are currently paying $5 per month (all we can afford) and switched to a new dentist.
