Amalgam fillings, also known as silver fillings, are a type of dental filling that has been used for over 150 years to restore decayed or damaged teeth. Amalgam fillings are made from a mixture of metals, including silver, tin, copper, and mercury.

There are some concerns about the use of amalgam fillings due to the mercury content in the mixture. While the amount of mercury in amalgam fillings is generally considered safe, some people may be concerned about potential health risks associated with exposure to mercury.

It's important to discuss the pros and cons of different types of dental fillings with your dentist to determine the best option for your individual needs and preferences. If you have concerns about the use of amalgam fillings, your dentist may be able to offer alternative options, such as composite fillings, which are made from a mixture of plastic and glass and are tooth-colored for a more natural appearance.
