For decades, silver-coloured dental amalgam was the standard material used to repair cavities. While durable, these fillings are increasingly being replaced by modern composite resins, often referred to as "white fillings." Beyond the obvious aesthetic differences, there are several functional and clinical reasons why patients in Stafford are choosing to upgrade their old silver restorations to more modern, tooth-coloured alternatives.
Aesthetic Seamlessness
The most immediate benefit of white fillings is their appearance. Composite resin can be precisely matched to the shade of the natural tooth, making the restoration virtually invisible. This is particularly advantageous for fillings in the "smile zone" or for patients who feel self-conscious about the dark metallic look of amalgam when they laugh or speak.
Preserving Natural Tooth Structure
The application process for white fillings is fundamentally different from that of silver fillings. Amalgam requires a "mechanical lock," which often involves removing more of the healthy tooth structure to create a shape that holds the filling in place. In contrast, composite resins bond chemically to the tooth. This allows the dentist to be more conservative, preserving more of the natural enamel and strengthening the overall structure of the tooth.
Temperature Sensitivity and Durability
Metal is a conductor, which means silver fillings can expand and contract when exposed to hot or cold foods. Over time, this movement can create micro-fractures in the tooth or cause the filling to pull away from the edges, allowing bacteria to enter. White fillings are more thermally stable and do not undergo the same degree of expansion, which can reduce post-treatment sensitivity and protect the tooth's integrity.
Modern dentistry prioritises both health and aesthetics. Whether replacing an old, failing amalgam filling or treating a new cavity, white fillings offer a durable, conservative, and beautiful solution. For those in Stafford looking to modernise their smile, a routine check-up can identify which old restorations might benefit from an upgrade.
