Device fee + monthly fee of 50,000 won + screws 600,000 won + retainers 400,000 won came to about 5-6 million won, I think. There were periods in between when I couldn't go, so it might not be exact lol. I had 2 upper teeth extracted, and while getting braces, I also had my upper and lower wisdom teeth removed. I'm very satisfied with the result. I originally had malocclusion and a deep bite, so I couldn't really bite food well with my front teeth, but now I can bite noodles off well too. I also fixed my habit of covering my mouth when I smile hehe. It was such a severe case.
I'm brushing, flossing, and using a Waterpik, and I wear my retainer once every two days (I should wear it every day, though.. hehe). So far it's being maintained well! I'm the type who gets cavities easily, so I'm brushing diligently. During the orthodontic treatment, it was hard because I couldn't even eat meat well, but now that it's over, I'm so happy!!
