I advise you not to go to Qingdao Stomatological Hospital. The whole hospital is very ordinary, and it costs a lot of money, not once, but once. Qingdao Stomatological Hospital is good, but I remember to bring a retainer after the whole operation, because I didn't bring it, so I have more experience. In fact, the mouth is very resistant and there will be no problem. The general field of ceramics should be carefully grasped by people, as well as itself. And it's not completely invisible. Steel wire is still silver, which can be seen from a distance ~ generally about 4000-4500 made in China ~ about 5000-5500 imported ~ more than 6000 porcelain is my experience, I hope I can help you ~
