Which hospital is better for Mianyang orthodontics? How much is the charge? I am 25 years old.

Depending on what kind of appliance you choose, it usually costs thousands of dollars, but it doesn't look very beautiful and the mouth is not so comfortable. It is the kind of general metal, and there are tens of thousands of good ones. This appliance looks less obvious, and your mouth will be more comfortable. What matters is what kind of electrical appliances you choose. I'm not very familiar with Mianyang, sorry.
