1. Dental fillings are good for children. Fillings can prevent food debris from being stored inside the cavity, and can also prevent the symptoms of tooth pain. If a child has caries, you should actively and promptly take the child to the hospital for filling to prevent caries from developing more and more seriously, which will bring unnecessary pain to the child and even affect the development of the child’s teeth. 2. It should be noted that the filling is not to bite too hard food within 2 hours, because the material used for children’s dental fillings is generally glass ionomer, its curing time is longer, you can not eat too cold, too hot food within a week. In addition, the day after the filling is not allowed to brush the teeth, usually just after the filling, the teeth of the material is not very strong, this time if you brush your teeth, then it may lead to the filling of the material breakage.
