Hello, my teeth are deformed. I have made three cobalt-fused-to-crown porcelain teeth, all of which are healthy living pulp teeth. The processing factory for quality assurance writing is Yiwu Jiawei Vadente. ... The factory you mentioned uses a brand of a product of a big international company, which is somewhat vague, and the trademark and brand name of this company must have been registered, which means it is impossible to have this company in China. Let's just say that your porcelain crown is made of this company's materials.

As for how many years the porcelain crown can be used, in fact, the main attention should be paid to cleaning and avoiding trauma. Under the condition that the porcelain crown is made by doctors, it can be more than 2 years.
