Preformed metal crown – adjustment & fit

Preparation of a tooth for a crown needs to remove much of the tooth’s tissue, including parts that might still be healthy and structurally sound. All materials which are currently available for making crowns are not as good as healthy, natural tooth structure, so teeth should only be crowned when an oral health-care professional has evaluated the tooth and decided that the overall value of the crown will outweigh the disadvantage of needing to remove some healthy parts of the tooth. This can be a very complex evaluation to make, so different dentists (trained at different institutions, with different experiences, and trained in different methods of treatment planning and case selection) may come to different conclusions regarding treatment.Usually more than one visit is needed to finish crown and bridge work, and additionally time required for the procedure can be a disadvantage; the advantages of such a restoration, however, are more important than disadvantages.
