There are so many ways to tackle this, I guess I would start with a use case. Since I know absolutely nothing about dentistry, let me ask the question - what is the absolute dead simple work that seems like it could be automated? Knowing nothing, I suspect that things like teeth cleaning could be performed by a machine for most cases. You can imagine in your home having some kind of thing you stick your face in, open your mouth and a large amount of data is collected visually about your teeth. If there is a way to see plaque and calculus, ML would highlight that and say, “remove?” And you would say yes, then it would gently pick at your teeth, visually inspecting the whole way. You are probably pressing some kind of trigger the whole time, and seeing the machine work the whole time. This is so you have some sense of control and in an emergency you could just release the trigger. Of course this would only work for the standard cases, anything else would need to see a human specialist. Eventually in 40 years no one would trust the human - all use cases covered.
