The main reason is that the position of filling teeth is different, and the materials used are correspondingly different. Amalgam is usually used to fill big teeth, because big teeth are the main force of chewing, and amalgam is getting stronger and stronger. Composite resin is usually used to fill teeth near front teeth. Mainly due to aesthetic considerations, amalgam is black, and it will be ugly if teeth are filled. But composite resin is certainly not as durable as amalgam. This is the difference. Happy spring festival!
