Very pleasant and professional doctor and staff. Had several old fillings replaced. Anesthesia was slowly administered so that tissue damage would be minimized. Was badly startled when used some sort of drill that felt like was metal bouncing on the side of my teeth. Said he liked the implement because although bumpy would only target decay and not healthy tooth. There was an apology and change of instrument. Once I was out as anesthesia wore off started to feel a lot of pain. Noticed that the right side of my face was swollen. Felt quite distraught. Called them and went back because it felt as if the teeth on the opposite side of the work done weren't touching. They were...this seemed to be just a sensation. Drilled down the fillings a bit. Gave a prescription for tylenol with codeine. I was in tears from the whole experience. My face is a bit swollen and hurts to open my jaw. Feels bruised. I have never had an experience like this and would like to know if anybody else has. I wonder if the nerve was touched when the injections were being administered since my face is tender to the touch close to my upper jaw. I have been unable to work today.
