Conservative treatment in dentistry starts with the dentist's efforts to prevent the formation of caries, and extends to treating the caries before it progresses or to repairing the lost tooth tissue by cleaning the decay. The cavity (cavity) formed as a result of decay removal is closed with artificial filling materials and the old anatomical form of the tooth is tried to be recovered.
Various materials are used for filling. Filling materials used today; amalgam, composite materials (Aesthetic or Radiant Filling) and porcelain. Today, the use of amalgam (silver-containing and silver-colored) fillings is decreasing, while the use of natural tooth-colored composite and porcelain fillings is increasing.

Selection of Filling Material

Each filling material has its own advantages and disadvantages. Choosing the appropriate filling material for the case is a matter that the physician should pay attention to; It is a wrong approach to use composite fillings in every case because it is aesthetic. Amalgam is still the most harmless, longest lasting and cheapest filling material. Compared to other filling materials, they can be applied in a much shorter time and easily. Filling materials such as ceramic-based onlay or inlay fillings, porcelain coatings, gold and aesthetic (composite) fillings are both more expensive and require more treatment sessions. In cases where saliva isolation is made impossible during filling application, amalgam fillings are preferred. In patients with mental and physical disabilities who have the habit of clenching their teeth, amalgam appears as the first choice in back tooth fillings. Because the aesthetics of the teeth in the anterior region come to the fore, amalgam filling is not applied to this group of teeth. In addition, amalgam filling should not be applied in patients who are definitely allergic to mercury, which is a possibility that is much less than one percent.
