I saw her several years ago and she did a root canal on a couple of teeth. I recently started have a great deal of pain and my current dentist sent me to an endodontist and found that 2 drill bits were broken off inside the root. When I asked how often this happens he said that it happens less than 1% of the time for a professional endodontist but it happens more frequently when a general dentist does it. I now am faced with dental bills that will be well over $1,000 for the least expensive fix to the problem. She crowned a couple more of my molars and did root canals I didn't have any pain before these teeth were crowned and now I doubt if the root canals were needed in the first place
