Had root canal, inlay and cavity filled. Misdiagnosed twice. First, with a tooth that needed root canal. I complained of pain in this tooth and told him it felt infected. He examined it and concluded cavity was too small to be a problem. He decided to work on a different problem and treat the painful tooth at a later date. After insisting 3 times that he immediately work on cavity, he removed it and discovered that it required a root canal. Second, with 2 teeth that also required root canals. Both teeth hurt when I came in for exam. He examined teeth and concluded that they weren't infected, but merely injured and would stop hurting once they healed. But, these teeth continued to hurt for the next 6 months. He examined me twice more, each time concluding that he was fairly certain that the teeth were not infected. At 3rd visit, reluctantly suggested I see an endodontist. I did. Within 1 minute, the endodontist determined that both teeth required root canals and proceeded with them. He seemed surprised that my dentist had not been able to diagnose and solve problem, which he said was obvious. (He had used a dental probe and was able to easily poke through enamel into the pulp chambers of both teeth.) Otherwise, he did good work.
