Dentist bad service

So this past weekend I had a filling fall out. So I made an emergency dentist appointment on Monday. When I got there, the dentist seemed rushed. Which I understand. She didn't want to numb me since there didn't need to be any drilling other than to shape the filling. I went with it even though it hurt. She seemed like she wasn't doing a thorough job and was rushing through, but I didn't say anything since it was a last minute appointment.

Big mistake. The new filling just fell out again. I'm pretty sure fillings are not supposed to fall out two days after it is put in. And of course, being that it is Christmas, I'm traveling and everything is closed. They better not try to charge me when I go in again when I get home.
