Well as it relates to humans, typically at an orthodontist office you have the one licensed orthodontist and any number of dental assistants, and the license orthodontist can oversee the work of the assistants. The assistants do the majority of the work but aren't credentialed, but because they're overseen by the main orthodontist we regard the work as rising to a standard we associate with professional legitimacy.
I think the net result in these cases is that there's a lot more professional capacity to meet the needs of people who have braces.
I don't suspect AI is coming for our teeth anytime soon but there's precedent for it as an oversight structure that satisfies us of the legitimacy of certain types of work.
The assistants do stuff like flossing the braces and such but the ortho comes in to actually install and set them up. Its not purely oversight but a skill gap and what is possible given an amount of training.
