The lifespan of dental amalgam restorations, often referred to as silver fillings, is a significant consideration for patients and dental professionals. These fillings, composed of a metal alloy including mercury, silver, tin, and copper, are placed in teeth to repair damage caused by decay. The functional duration of these restorations represents the period during which they effectively seal the tooth, withstand biting forces, and resist deterioration.
Amalgam restorations have a history spanning over a century, offering relative affordability and durability compared to some alternative materials. Their ability to withstand compressive forces makes them suitable for restoring molars, which experience high occlusal pressure. The longevity contributes to their cost-effectiveness over time, reducing the frequency of replacement and subsequent dental procedures. However, factors such as patient oral hygiene, diet, and bruxism (teeth grinding) influence their performance and ultimate survival rate.
