They really try hard to sell you the 3D scan that's not covered by insurance. They made me feel unease of their intentions as medical service personnel. On top of that, the endodontist (Schneider) came across as narcissistic and disrespectful. When I asked about the recovering of my tooth after the procedure, he told me that it was biology we were taking about, not simple mechanics, as if I was too ignorant to comprehend what he had to say. I suppose I could have given him a brief explanation on the "simple mechanics" as a mechanical engineer, but I decided not to waste my time. I ended up going to a different endodontic office for my root canal retreat. I got a better quote and was never once told I need a 3D scan even if that office had the 3D scan equipment. Remember when a service is not covered by insurance it's probably not needed.
