Dental fillings are used to restore damaged or decayed teeth. They can be made of various materials, including silver, composite resin, porcelain, and gold. Silver fillings, also known as amalgam fillings, are one of the oldest and most commonly used types of dental fillings.
Silver fillings are made of a mixture of metals, including silver, copper, and tin, as well as small amounts of mercury. When the mixture is combined, it forms a durable material that can withstand the pressure of chewing and grinding. Silver fillings are typically dark in color and can be visible when you talk or smile.
In recent years, there has been some concern over the safety of silver fillings due to the presence of mercury. While the American Dental Association (ADA) and other organizations maintain that silver fillings are safe, some people choose to have them removed and replaced with other materials.
One alternative to silver fillings is composite resin, which is a tooth-colored material that can be used to fill cavities. Composite resin is less noticeable than silver fillings and can be a good choice for visible teeth. Porcelain and gold fillings are also options, although they tend to be more expensive than other types of fillings.
Ultimately, the type of filling that is best for you will depend on the location and size of the cavity, your personal preferences, and your budget. Your dentist can help you decide which type of filling is right for you.
