Dental fillings are filled and restored, and the steps of filling and restoration are generally tooth preparation, bonding, filling and curing of composite resin, as follows.
1. Dental preparation: removing caries, defective tissues or materials and fragile tooth structure, the scope of preparation is usually determined by the size, shape and location of the lesion.
2. Bonding: Using the acid etching-bonding technique or the self-etching bonding technique, the tooth tissue is acid etched and coated with a bonding agent to form a bonding layer.
3. Filling and curing of composite resin: the composite resin is filled layer by layer and then light cured layer by layer, after which the filling is shaped and polished.
It is recommended to visit regular medical institutions to receive professional treatment.
