The task of conservative dentistry is to keep your teeth alive and healthy. Tooth decay always appears unexpectedly and doesn’t need to hurt. The only way to get rid of it is to remove the entire damaged part of the tooth. The cavity resulting from this must be treated with a filling.
The filling material we use contains the smallest quartz, glass and ceramic particles. Due to different colours, highest aesthetic demands are met. The fillings are almost invisible. The tooth can be perfectly restored with special enamel and dentin materials.
To achieve a long durability, the plastic filling must be applied in many small layers to minimize the shrinkage of the composite during light curing. The process begins with enamel etching to roughen the surface of the tooth’s defect and thus achieve an optimal bond between enamel, dentin and composite.
The durability of a composite filling depends on the size of the defect. A larger defect is exposed to higher chewing force which can result in a shorter life span of the filling. Therefore, for larger tooth defects, a more extensive restoration like an inlay, a partial crown or a crown is necessary, depending on the degree of destruction.
For a long time, amalgam was the preferred treatment for caries. It is a metallic alloy of mercury, silver, tin, zinc and copper. Theoretically, amalgam meets all the requirements of a filling material because it is easy to process, durable and inexpensive. However, this material has become increasingly discredited as mercury can be released during chewing and some patients react with intolerances.
Due to the situation described above, we do not use amalgam, but intact amalgam fillings do not have to be removed if they are well tolerated.
Inlays are laboratory-fabricated restorations. They are usually suitable for larger defects. Inlays are made from a tough, ceramic material which resembles the natural colour of your own teeth and is attractive to view. After the caries has been removed, the resulting defect for the inlay is prepared and an impression is taken for the dental technician. The dental technician creates models in the laboratory and fabricates the inlay precisely and individually for the specific tooth. In a second appointment, this inlay is now adhesively cemented.
