Right now, I am sitting in an exam room at the dentist. I haven't visited a dentist in at least seven years...digital X-rays! They took 20 pictures, which would have been enough radiation to turn me into the Hulk a decade ago, but now the amount of radiation is small enough that the tech didn't even leave for some of them. TVs attached to the ceiling with Netflix whaaaaat? I don't have to try and have an awkward conversation with someone's hand in my mouth? I can just watch old episodes of HIMYM while the man works?!
Of course, none of the developments of modern dentistry are going to change the fact that he's going to want to remove my wisdom teeth when all is said and done. -_-
