You are playing Russian roulette with this dentist. Need to check out all of his reviews prior to patronizing his office. My father was a dentist; I know the minimum standard of care. Marcum's treatment of me resulted in ongoing pain, infection, bone loss and the eventual loss of the tooth. This was a routine root canal. His demeanor was angry. His treatment was brutal; there is no other way to describe it. He jammed the splint used to prop the mouth open, with the heel of his hand repeatedly. That only added to the pain that felt like having a root canal done without any anesthesia. I would cry; he told me that if I cried, he would send me away. I knew the nerve was exposed or I would have gotten out of that chair and run. I was trapped. There was no attempt at alleviating pain, only causing more. His staff stood by, mocking me. When it was over, I was still in intense pain for until I went to the ER the next morning. When I went to another dentist, she immediately acknowledged that I'd been traumatized. I went to another endodontist who volunteered that the evidence pointed to iatrogenic or physician caused harm. He wrote a letter detailing infection and bone loss and had to extract the tooth.
