No, it is rather substantially cheaper here. Until recently I had not been wowed by Japanese dentistry, so I got some long-delayed work done last time I was in America on a cash basis. (Happily, when one of the fillings that cost $~X00 popped out and I had to visit the first dentist I found on Google Maps by my office, I had a wonderful experience but for the searing pain of losing a filling, and will be going to him from now on.)

None of the above is intended as a commentary on the relative merits of national health insurance.
