Hello, at present, the best filling material is light-cured composite resin, which is often called nano-material. Both aesthetics and functionality can be guaranteed, and the teeth can be used directly after filling. Resin is also divided into many grades, and the price is different. If the tooth itself is deeply damaged, it needs to be filled with resin first, otherwise it will be irritating. It is recommended to go to Weihai local regular stomatological hospital for treatment.
