I had orthodontic treatment there for 5 years, but my bite wasn't right, so I looked into re-orthodontic treatment. But other dentists said they couldn't re-orthodontic treatment because the roots were too short, and if I did, my teeth would fall out. I wanted to see if there were other cases like mine, so I searched all the reviews and Naver cafes that are famous for orthodontic treatment. I looked it up and there were a lot of similar cases.. Be careful. I paid 700 but I only lost my money.
