A dental restoration, commonly referred to as a filling, is a material used to repair a tooth damaged by decay, often caused by cavities. The visual appearance of these restorations varies significantly depending on the material used. Amalgam fillings, one of the oldest types, are typically silver-colored. Composite fillings, designed to match the natural tooth color, appear white or tooth-colored. Gold fillings exhibit a characteristic gold hue, while ceramic or porcelain fillings also strive to blend seamlessly with the surrounding tooth structure.
The significance of a dental restoration lies in its ability to halt the progression of tooth decay and prevent further structural damage. By filling the cavity, the restoration seals the tooth, preventing bacteria and food particles from entering and causing further deterioration. Furthermore, fillings can restore the tooth’s shape and function, allowing for proper chewing and speaking. The use of restorative materials dates back centuries, with evidence of rudimentary fillings found in ancient dental remains. Modern dental materials offer improved durability, aesthetics, and biocompatibility.
