What is a disadvantage of cast gold inlays?

A disadvantage of cast gold inlays is that they may display metal, which can be a significant aesthetic concern for patients seeking dental restorations. Patients often prefer materials that blend in seamlessly with natural tooth enamel, which can lead them to favor more tooth-colored options like porcelain or composite resin. Metal displays, particularly in visible areas of the mouth, can detract from the desired natural appearance, making cast gold inlays less appealing in cosmetic considerations.

While the other factors, such as corrosion resistance and low deformation, are actually positive attributes of cast gold, they do not address the key issue of aesthetics. Additionally, the complexity of the restoration process is not necessarily a disadvantage when considering the longevity and durability of the resulting restoration. Therefore, the metal display aspect stands out distinctly as a disadvantage in the context of patient satisfaction and aesthetic outcomes.
