It's hateful. Don't do it for others if you can't do it well. Nowadays, doctors only know how to make money and don't pay attention to medical ethics. How hateful. What I absolutely think is that he is too cruel. I also have little tiger teeth struggling with what to do. Seeing your example really scares me. It's not a matter of wasting money. It used to take two years to correct teeth, and every tooth hurts. How painful it is. Now the pain has doubled. The doctor's mistake should be punished when this kind of mistake happens.
