how many times should i let my dentist "adjust" my teeth?

I had a crown replaced on #14 in August. No pain, no adjusting necessary. She did notice an old crown on 13 was cracked and said it would probably break off. It did. Had a new one put on November 7th. I had no problems with the temporary but when the permanent crown was put on it didn't feel right. I heard and felt a "click" when she glued it on. I told her it didn't feel right. She said it would feel a little tight at first. The next morning it felt like a wedge had been put between my teeth. My bite on my whole left side was off. My gums were irritated and I felt a lot of pressure and pain in the upper left quad. I went back to her 5 times for her to 'adjust' my bite. Still had a lot of pain and pressure. Told her I felt a ridge or something on the margin on 13. She looked, but did not probe and said there was nothing there and that there was a good seal. By then it was Christmas break and I couldn't see her for another 12 days! I was still in a lot of pain and by now I was only hitting on 14. Three days later I took some floss and dug and dug under the gum between 12 and 13 and out popped a piece of cement! Instantly the pressure and gum pain was gone! So I think my teeth went back to their correct position, but by now the rest of my teeth had been 'adjusted' so many times my bite was way off and the only tooth I was touching  was 14. It hurt very much. When I went back to her after the break she sent me to an endo for a root canal on 15 which had been sensitive to hot and cold for a few years. She wanted me to see this doctor because he had some occlusion training. He did the root canal and also 'adjusted' 14. Now I am only hitting on my front teeth, not on  my molars. What are my options? Do I go back to the endo and get more 'adjusting' or do I have to see an ortho? and who pays for all of this?
