What are silver fillings made of?
Silver fillings, also known as dental amalgam fillings, are made from a combination of materials that include silver, tin, copper, and mercury. Despite the name, silver fillings are not entirely composed of silver. In fact, the silver content makes up only a small portion of the mixture.
One of the key components of silver fillings is mercury. Mercury is used in dental amalgam fillings because it helps make the material pliable during the filling process. When mixed with the other metals, it creates a strong and durable compound that can withstand the pressures of chewing and biting.
The silver in the filling helps with durability and strength, while the tin adds to the material's resistance to corrosion. Copper is used to increase the filling's strength and to help with its durability over time. Together, these metals form a stable and long-lasting filling that has been used for over a century in dentistry.
While silver fillings have been a popular choice for dental fillings due to their strength and affordability, some concerns have been raised about the mercury content. Despite these concerns, numerous studies conducted over the years have shown that the amount of mercury released from dental amalgam fillings is minimal and falls well below safety limits set by regulatory bodies such as the FDA.
It is essential to note that when mercury is combined with the other metals in dental amalgam fillings, it forms a stable compound that is generally considered safe for use in dental restorations. The American Dental Association and the World Health Organization, among other dental associations globally, have deemed dental amalgam fillings to be a safe and effective treatment option for cavities in both adults and children.
In conclusion, silver fillings are a durable and long-lasting option for dental fillings. Despite containing mercury, amalgam fillings are considered safe for use in dental restorations by various dental authorities. If you have concerns about silver fillings or any other dental treatment, it is best to consult with your dentist to discuss your options and address any questions you may have.
