While I 100% agree with what you wrote, I'd just add that it does seem in my own dental visits over my lifetime that there have been real advancements, too. But yes, I agree, hard for non-expert to parse.

Seeing SLA 3D printers at my dentist's office was pretty cool. Apparently they use them for a variety of fixturing and jigs, and have a workflow that includes a handheld scanning unit that SLAMs to generate a solid model of the patient's teeth.

		I have 4 crowns, 2 done using moulds, 2 using the 3d scanner. Same doc, same office. The moulded ones were ok with some adjustments, but the 3d scanned ones were perfect since day 1. I'm happy with the progress in dentistry.

I'm surprised how many low-hanging fruit issues are still not solved. So many dentists use cold or tap water for their rinse sprayer despite the fact that many people have temperature sensitivity issues with their teeth. Having lukewarm water would be trivial but I've yet to go to an American dentist that does it.

Can you share some specifics?
