You are right, my exposure to medicine is pretty cut and dry, so I was speaking from my experience. As well I did not mean it as derogatory towards medicine practitioners. My summation was more geared towards routine surgery which for the majority of us, is what medicine is, check-ups and routine surgery. Most of us are fortunate to not have medical anomalies that require anything other than routing medical attention in which case prices are pretty cut and dry. My point was when a doctor recommends a path of treatment they usually have a comfort level with that treatment and it's effectiveness. In your case the filling, the root canal and the serious work where three separate projects. In the development world, you would get the requirements for the filling and the root canal would feature creep in as the filling was being done. That was my point, was that doctors (for the most part) have pretty fixed problem sets like root canal where developers have different problem sets for each new project.
