I tried to use it for 30,000 miles to find a hospital, but I couldn't use it because it wasn't there...Anyway, the doctors here are kind, but the nurses are a bit unfriendly. Of course, the nurse looks so busy that it's hard, so it's understandable, but it still makes me feel bad sometimes? Anyway, he is very careful, asks a lot of my opinion, and cares about the patient a lot, but at the last stage, the intermaxillary rubber band, I work hard and the 4th right upper and lower teeth can't reach. I also had a tooth extraction, but it still protruded. Face shapes and things like that are prettier, but the cost of correcting them is not cheap, so everyone should choose carefully.
