The choice of filling materials depends on the degree of tooth defect, the needs of patients and the advice of doctors. The following are some common filler materials and their characteristics:

1. amalgam: amalgam is a traditional dental filling material with high strength and wear resistance, which is suitable for the restoration of posterior teeth. However, its color is not beautiful and it is very irritating to dental pulp, so it may not be the best choice in some cases. 2. Composite resin: Composite resin is one of the most widely used dental filling materials in clinic at present, and its advantages include wear resistance, difficulty in falling off and beautiful appearance. According to its composition and performance, it can be divided into nano-resin, general-purpose resin and other types.

3. Glass ion cement: Glass ion cement is composed of glass ions and acrylic acid, which has good adhesion and the ability to release fluoride ions and can prevent dental caries. Its disadvantage is that its strength is relatively low and it is easy to wear or crack.
