I had orthodontic treatment a few years ago and it finished, but the retainer (wire) at the back keeps coming off. Every time it came off, I visited the clinic, and each time they said this had come off too and that had been replaced too, so it cost over 100,000 won. I probably spent over 500,000 won? Now my home is far from Gangnam too, so I went to a clinic near my house, and unbelievably, it was 20,000 won with 1 year of after-service included! Phew, I guess I went there for nothing.
