This afternoon when I went for my appointment, they got me in early, gave me a check-up, gave one of my fillings needed "maintenance", gave me a cleaning (also called a "scaling": normal cost: 70,000) then told me that b.c they did the original filling, it was covered by a 5 year "A/S" (After Service) warranty. Then, after I told them that I was going back to the States for good, they gave me copies of my dental records.
Total cost of the visit: 30,000 won. (a special "home going" discount)
Lately Korea, you've been rocking my world.
