If all your teeth fall out, you must put them in. If you have teeth, you have to hang a set. A set is as expensive as a tooth. I guess I'll have to insert porcelain teeth in the end. The cheapest Ni-Cr porcelain 260 yuan, the middle-grade Co-Cr porcelain 460 yuan, and the best zirconia all-ceramic teeth 1500 yuan. These are all preferential prices, and Tongji Affiliated Hospital may be twice as expensive.
