Our classmates also went to Guanghua to make porcelain, but she only had two front teeth. She didn't go to see Professor Lin, and it turned out very well. I did it with her at that time. Before doing it, the doctor will ask you many questions. Generally, doctors don't recommend making porcelain teeth, because it will hurt teeth after all, if you really make up your mind to do it. You don't have to appoint a professor, but you can see an experienced expert.
Personally, I think Guanghua has a good environment and the nurses are very kind. Of course, you can consult first.
