Dental restorative materials are utilized to repair teeth damaged by decay or trauma. Two common choices for these materials are metallic fillings, made primarily of a combination of silver, mercury, tin, and copper, and tooth-colored fillings, composed of plastic resin reinforced with finely ground glass particles. Each material possesses distinct properties influencing their suitability for specific clinical situations.
The selection of a dental restorative material is influenced by factors such as durability, esthetics, cost, and potential health concerns. Metallic fillings have a long history of use and are known for their strength and longevity, particularly in load-bearing areas. Tooth-colored fillings offer a more natural appearance and bond directly to the tooth structure, potentially requiring less removal of healthy tooth material. The cost-effectiveness of metallic fillings has also been a significant factor in their widespread use over time.
