Frankly, I see a missing filling as an emergency appointment. To me, a no brainer, fix the emergency, and then address whatever else. If they couldnt handle that, I dont know what else to say, other than you did the best YOU could with them. This is exactly how I met my present dentist, and I love him. I knew I was overdue for a cleaning, but hated the dentist I was seeing (arrogant), and hadnt gotten around to finding another yet. I have plastic in one of my upper front teeth (not THE front teeth, but one next to them) ... dont know how, but in my sleep, I had stretched my jaw ... vaguely remember doing it ... and sheered the side of the tooth right off (filling and part of the actual tooth) and woke right up with the chunk still on my tongue. Hit the phone book at 9 am, and got an appointment for the next day. He took a single xray of the tooth that needed the work, fixed the tooth, and afterwards, told me to make another appointment for the cleaning I needed, and full xrays.
