First, the number of cavities. Dental fillings are charged according to the number of teeth. Generally, the more cavities, the more money you spend.
Second, the degree of tooth decay. It's cheaper if it's only superficial caries. Just fill your teeth. If it is deep caries, root canal treatment is needed, and the cost will be much higher.
Third, filling materials. At present, the relatively safe and beautiful filling material is composite resin, and the price is not expensive, generally about 100 yuan. If it is other glass ions, amalgam, etc. It may cost less, but it is more irritating to the gums and ugly. thank you
