What’s the Difference Between an Amalgam and Composite Filling?

When you have a cavity, your dentist in Woodbridge, VA, should recommend fillings to prevent dental decay from spreading. Fillings help restore your teeth so you can eat and drink comfortably again.

The dentist may ask you whether you want amalgam or composite fillings. These two types of fillings are very different from one another. Knowing the differences and choosing the right fillings can help you care for your teeth.

Amalgam Fillings

Amalgam dental fillings have been used to fill cavities for decades. Amalgam is made from a combination of metals, giving these fillings a silvery color when they’re first installed. Over time, the amalgam turns a darker color. After many years, the amalgam may be dark gray or black.

Amalgam fillings are long-lasting and durable. They can last for 15 years or more, and for some people, they can last for decades. Amalgam fillings are most commonly installed in the back of the mouth, where they are less noticeable.

Composite Fillings

Composite fillings are made from tooth-colored resin and blend seamlessly with tooth enamel. Composite fillings are often preferred by patients filling cavities toward the front of the mouth because composite resin is virtually impossible to distinguish from tooth enamel.

Composite fillings do not last as long as amalgam fillings. Typical composite fillings last about seven years and then need to be replaced. If you’re concerned about installing a filling that will last as long as possible, consider composite fillings.

Insurance does not always pay for composite filling installation. If you’re on a budget and concerned about getting a filling as inexpensively as possible, you may need to consider amalgam fillings.
