I had a root canal on the left lower molar. I went to the get prepped for a temporary crown at which time I was told I would also need fillings for teeth above the root candled tooth and 2 beside them. I agreed that once the temporary crown was to be fitted then I would get the fillings at the same time. I went to get my fillings and temp. crown done by the time I got home I was in excruciating pain. I could not bite down and my gum around the crown was super sensitive I went back in a few days to fin out why. The fillings needed to be filed down and there was too much cement at the temp crown. It did was a bit until my bite was again disturbed. I went back for my bite to be adjusted and as soon as i got home the bite was again disturbed. I finally went back 2 weeks later to get my permanent crown even though my gum was very inflamed and filled teeth we very sensitive. The permanent crown was placed and again my bite was adjusted. One week later I am still in excruciating pain. I cannot bite or chew on my left side. The filled teeth are extremely sensitive to cold. The crowned tooth is even more sensitive to cold and leaves a throbbing pain. My gum is swollen and inflamed I am practically living on ibuprofen. at the base of the crown I see a silver line which looks like metal. I went to the offices in great condition and left now in pieces. I am so frustrated with the pain and I feel they cannot correct it. What are they doing wrong and what should I suggest to them and are these feelings normal.
