I have had nothing but problems from the time that I was fitted with the temporary crowns to the permanent ones that I have now. My temporary fell out and had to be cemented with permanent cement. When I was ready to have the permanent crowns put in, he removed the temporary crown and broke the rest of my tooth off that was supposed to be the foundation for the permanent one. He installed a post, and cemented the permanent to it. Within a week or so the permanent crown fell off the post. He re-cemented the crown and when he did he set the tooth crooked. I have had fitting problems where as the teeth grind against my natural teeth. Currently the crown that contains the post is now loose. Personally I will not go back to him again. I have given him several opportunities to fix his mistakes, and every time I go back he creates another problem for me.
