I agree, for some reason dentistry and orthodontics seem far more technologically advanced than the rest of medicine. In addition to handheld x-rays like you mentioned, I’ve seen dentists/orthodontists use 3D printers, 3D scanners (e.x. iTero Element) and modern composites. Small sample size, but all the orthodontists and dentists’ offices I’ve been in are clearly embracing new technology as much as they can, while every doctor’s office I’ve been in has seemed like it could be a hundred years old. I wonder why that is.
The cynic in me suspects it's because insurance companies and employer-provided insurance hasn't completely mucked up the market the way it has with healthcare. Sometimes I wonder if America's "best" (least resistant) path to single-payer healthcare is to start smaller scale with universal coverage for vision & dentistry and then slowly expand coverage from there.
