Yes, I first made porcelain teeth because there were cracks in the teeth, and then they became cavities. The dentist polished off the bad part of my teeth and put on porcelain teeth. If the bad part is not polished off, it will continue to decay your teeth in the ceramic teeth. Besides, I remember that the doctor broke the nerve of my tooth. Now, my tooth can't eat hard things, or the root of the tooth will hurt. I made 4 yuan for the porcelain tooth. Why do you make ceramic teeth?
