Oh sure you have the X-ray and some fancy computer, but look at the tray of picks and sharp pointy objects they use. How can they not have some kind of laser, nanobots or something to clean your teeth? Are we not in the 21st century? If you make tools for the medical field you need to come up with something that was not used during the Spanish Inquisition.
I'm glad I no longer have to do that awful tasting fluoride mouth piece thing. If you do not remember or do not know, back when I was a youngster way back in the early 80s, they had a mouth piece and they would fill it with this.... ooze and put it in your mouth. It was full of fluoride and suppose to help keep cavities away. It tasted awful, and they tried masking the taste with crappy flavors. The first was grape and I hated grape, but they thought all kids love grape. So I had this nasty substance in my mouth that had a hint of grape. I wanted to throw up every time I saw that stuff. As far as I can tell that's the only improvements in the dental field in the last 50 years.
Maybe the next time I visit they will have created something less painful, who am I kidding it'll still hurt.
