Dental amalgam, often referred to colloquially as “silver teeth,” is a durable filling material used to restore teeth damaged by decay. Composed of a mixture of metals, including silver, mercury, tin, and copper, it effectively seals the prepared tooth cavity, preventing further bacterial infiltration and subsequent decay. For example, if a molar develops a cavity, a dentist may remove the decayed portion and fill the space with dental amalgam to restore the tooth’s structure and function.
The primary advantage of this material lies in its strength and longevity, making it suitable for restoring posterior teeth which withstand significant chewing forces. Its relative affordability compared to other restorative materials, such as gold or composite resins, has also contributed to its widespread use throughout history. Dental amalgam has a long track record of clinical success, providing a reliable and cost-effective option for dental restorations. Concerns regarding mercury content have been raised, leading to ongoing research and alternative material development, but amalgam remains a viable option in many cases.
