I'll probably never have a chance to go here again, but who knows?
In Japan on DH's and my honeymoon, I had a bit of a sore tooth. Nothing to worry about. I had a dentist appointment booked for after we got back (the local dentist couldn't get me in any earlier). Well, while we were away, it got much worse, to the point that all the over-the-counter analgesics wouldn't do a thing (maximum safe dosage had no effect), and I ended up spending one night sobbing on the bathroom floor, unable to sleep due to the pain and half-deaf from the deafening throbbing in my head. (DH had gone ahead at this point for logistical reasons, so I was all on my lonesome for 30 hours.) I actually tried to pull the tooth out in desperation several times, but it's a molar near the back and couldn't (fortunately! You absolutely should not do this, as it can make things a lot worse).
So I Googled "dentist" and our hotel's address, and as soon as work hours began, walked to the nearest one, about 3 blocks away. The dentist was very sympathetic--when I said that I couldn't sleep because of the pain, and that I hadn't eaten anything solid for two days, he declared it "emergency treatment" so I'd get to be seen immediately. The tooth was infected, and he was very patient as I stumbled around dental terminology in Japanese that I'd only just looked up that morning. The equipment was like something from out of a sci-fi movie, as well. Nothing close to it in Australia. It was also the only dentist appointment I've ever been to where they actually wait for the anaesthetic to take effect (it takes ~10 minutes) before drilling away, so I never felt a thing. At all other dentists I've seen, they inject, drill/whatever, and you only start feeling numb on the way home.
Locals get an automatic 70% off all medical and dental stuff (government healthcare system), but since I wasn't local, he felt bad that I'd have to pay full price. Students also get 70% off, so he asked if I was a student or anything back in Australia (even though technically I'd need to be a student in Japan...) but I wasn't, so full price it was. He was very apologetic.
The cost of a tooth removal, two shots of anaesthetic, X-ray, filling, two days' worth of analgesics for me to take home just in case, and the other things he did was, in Australian currency, $50.30. And he was apologising!
I was so out of it from pain that I didn't even catch his name--I just called him, "Dr. Dentist." But he was the best dentist I've ever been to.
