My dentist uses very little new tech, it would seem to me if you could build a robot that could inspect the mouth visually, perhaps perform parts of a cleaning or other repair much faster and more comfortable than todays procedures. This robot could be deployed remotely or even home. Toothache? Buy this robot at Walgreens and a AI will tell you what the issue is(get a human opinion for only $99 more!). Collecting lots of images would let you at some point create a ml model of defects that could then be identified by the machine. While the science of ml is complicated, collection and creating models is much less complicated. The tech is great but this has the potential to solve the real problems and bring automation.
