Dentist appointment today

Today I had to go to the dentist to have some fillings repaired. The dentist that worked on me was new to the practice. She was a little bit rougher than the old one that did the original fillings. The shots she gave me hurt so much. I have never had that much pain at the dentist before. I think the worst thing about the whole appointment was my jaw about to pop out of its socket. I have problems with my jaws locking and popping on me anyway. Right now it is killing me as the shots are wearing off. I can bearly open it wide enough to take a bite of anything.
