Should You Replace Your Metal Fillings?

If you’ve had cavities filled years ago, there’s a good chance you have silver-colored, or amalgam, fillings. At Alma Dental Care in Petaluma, CA, Dr. Maria Serrano often gets one specific question from patients with older dental work: Should I replace my metal fillings? The answer depends on a few factors—including how the filling looks, feels, and functions today.

The Basics of Metal Fillings

Metal fillings, also called amalgam fillings, have been used in dentistry for over a century. They’re strong, long-lasting, and relatively affordable. Made from a combination of metals like silver, tin, copper, and mercury, they’ve helped preserve many smiles over the years. But times—and materials—have changed.

Today, tooth-colored composite fillings are more common, especially for patients who prefer a more natural look or have concerns about the aesthetics or makeup of metal fillings.

When Replacement Might Make Sense

Not all metal fillings need to be replaced. If they’re in good shape—no cracks, no signs of leakage, and no discomfort—Dr. Serrano may recommend leaving them alone. However, if the filling is worn, loose, or contributing to cracks in the tooth, replacement may be necessary.

Some patients also ask about removal due to cosmetic reasons. If a metal filling is in a highly visible spot, replacing it with a composite filling can improve the appearance of your smile. Others have concerns about the mercury content. While the American Dental Association deems amalgam fillings safe, you can still choose to have them replaced if it gives you peace of mind.

Composite vs. Amalgam: What’s the Difference?

Composite fillings are tooth-colored and bond directly to the tooth structure, making them ideal for visible areas. They require less removal of healthy tooth during placement. However, they can wear slightly faster in high-pressure chewing zones.

Amalgam fillings, though more durable in certain back teeth, can expand over time—sometimes leading to cracks or stress on the surrounding tooth.
