Horrible dentist

This dentist at first seemed really nice and then after the first consultation the trouble began. He kept on arranging more and more appointments even though I had expressed my concern about finances, since I was going overseas to teach for a year. Each time I visited I told him and made it very clearly known that something did not feel right with the treated teeth and that since he worked on my teeth they were really sensitive to any and all temperatures which was never the case before. He kept on saying it was fine and that it was normal. I kept complaining because it didn't feel right and it was like he got annoyed at me saying how my own mouth felt. Skipping ahead a little, I am overseas and the teeth that were worked on are giving major problems. One has a hole in the filling and the other, that I had stated while in the chair at his offices had made an awful crack sound when I bit down on the new filling, now has a huge crack at the back of the tooth and I might lose part of my tooth. Which is horrible for a girl! Then not only did he use every last cent in our medical savings, but I also received an extra bill. I made arrangements with him because of the uncer*****y of my overseas accounts, but when my teeth kept causing me pain and giving me even more grief, I messaged him and told him that I would not pay seeing as the services he was meant to provide, namely fixing my teeth, were not properly done. On the contrary, he made them worse! Next thing I know I receive a message from his lawyers demanding the payment. This doctor is not a good dentist and I regret ever going to this man.
