Over the years Elaine Rodgers has performed multiple root canals for me. Each and every one of them failed and I lost the tooth within 8 years. The oral surgeon who performed the extraction of the failed root canals was amazed to find that in each one of them there was a broken piece of file. This may have been the primary factor in the failure and loss of these teeth. The root fractured as the broken file end was left embedded in the root.
The form Dr. Rodgers as patients sign prior to working on them explicitly releases her from just such damage. Was she incompetent, I don't know? But I do know I lost these teeth and had no recourse.
