We can broadly divide it into aesthetic fillings and functional fillings
Aesthetic fillings are generally in the front teeth, and helps one to look aesthetic. The functional fillings on the back teeth helps to have a proper bite. Restorations or dental fillings are used to replace the part of the missing tooth which is carious or to prevent decay that may cause pain in future.
Fillings can also be preventive in kids called as preventive fillings /pediatric restorations to prevent caries from occurring.
Generally, the newer fillings materials also have fluoride in them which prevents marginal leakage and prevents secondary caries.
