I had a root canal on tooth #19. Dr. Pollack did not use a microscope during treatment and therefore could not detect the length of the root canal. The entire canal was not treated causing me to have a retreatment. My insurance company would not pay for retreatment - a cost of $3000.00 to me. When I contacted the office for a remedy I was told that he had reviewed the case notes and there was nothing wrong with the tooth or his work. His practice is not up to currrent standards. He does not accept responsibility for his work or correct mistakes.
