At present, there are three commonly used filling materials:
First, silver amalgam. This is an ancient filling material with black color, good wear resistance and poor uniformity. Can not be used to fill the front teeth and beautiful tooth surface, it is best to fill the back teeth, especially the maxillofacial region.
The second category, resin materials. This material has many advantages, such as good color, neatness and wear resistance, and can be used for both front and rear teeth. However, it has a disadvantage that there is a tiny gap between the filling material and the tooth surface after filling, which is also called polymerization shrinkage.
The third category, glass ions. The color of this material is very good, it is white. The cleanliness is good, but the wear resistance is not enough. Its ingredients contain fluorine, which can prevent dental caries, so it is generally used to fill the dental caries of deciduous teeth.
