A filling is a dental restoration used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth will be removed and then filled with a composite filling. Fillings are sometimes called “restorations” because they restore the functionality and appearance of a tooth.

Types of Fillings

There are different types of materials used to serve the purpose of filling, such as:

Amalgam Fillings

Amalgam fillings are made of a combination of metals, including silver, tin, and copper, along with mercury. Mercury is used to increasing the durability of the filling. These fillings make a good choice for back teeth since they’re the least expensive option. However, the mercury content makes these fillings less safe for young children.

Composite Fillings

Composite resin fillings are tooth-colored and used to treat small- to medium-sized cavities. The resin is cured with blue light, hardening the resin and forming a tight bond with the tooth. Composite resin fillings can last 10 to 15 years.

Another benefit of using composite resin fillings is less tooth structure is removed compared to amalgam fillings.

Porcelain Fillings

Porcelain fillings are made of a combination of ceramic and plastic compounds. They are very strong and can withstand the pressures of chewing. They also match the color of teeth, making them popular for use in visible areas of the mouth.

Porcelain fillings cost more, but they blend in with the patient’s smile.

Glass Ionomer Fillings

Glass ionomer fillings, also known as dental composite resins, are one of the most commonly used dental fillings in America. They are made from a mixture of acrylic resins and glass powder, which gives them their translucency.

Glass ionomer fillings are a popular option because they offer several benefits. They are highly resistant to wear, which makes them durable. They are good at resisting fractures, which keeps your dental filling in place. It’s also very resistant to staining.

Gold Fillings

Gold fillings are dental restorations made from an alloy of metals, including gold, silver, copper, zinc, tin, and sometimes palladium or platinum. These metals are mixed with mercury or palladium before being heated and molded into the desired shape.

A gold filling is a good choice for restoring a tooth that has endured a lot of decay. These fillings can withstand chewing forces well.
