I only had one experience with Dr. Rauth, but I was impressed with Dr. Rauth's competence (as far as I can tell) and his ethics. I didnt actually have a root canal done although I was scheduled for one. After drilling into my tooth, he determined fairly quickly that the root canal procedure would be futile due to a baseline fracture in my tooth. So he immediately referred me to an oral surgeon to have the tooth removed. He explained that had he done the procedure, the tooth would have lasted another 6 months before becoming reinfected. So I feel he has integrity. I really have no idea if his charge was expensive since I didnt compare prices.
