Generally, the price of filling teeth should be less than 500. I suggest you go to Zhu Weihua Dental Clinic in Cheng Nan Garden. Very good. I used to have my teeth fixed there. Generally, if a tooth is filled, it will be disinfected at first, and then it will be filled at home for a few days. If the substance on the tooth falls off, you can call directly without delay. Generally, cavities are filled with gypsum. If you don't fill it in properly, it will taste like plaster and be super disgusting.
