White vs. Silver Fillings: Which is Better for You?
Dental FillingsBy February 10, 2025
For over a century, silver amalgam was the king of cavity repair. Today, tooth-colored composite fillings have taken over. But is newer always better? Understanding the pros and cons of each material can help you make an informed decision for your smile.
Silver Amalgam Fillings
These are made from a mixture of metals including silver, tin, zinc, copper, and mercury.
- Pros: Extremely durable (lasts 10-15+ years) and less expensive. They withstand heavy chewing forces well.
- Cons: Dark color is highly visible. They require removing more healthy tooth structure to hold the filling in place. They can expand and contract with temperature changes, potentially cracking the tooth over time.
White Composite Fillings
These are made of a glass and plastic mixture that bonds directly to the tooth.
- Pros: Invisible (color-matched to your tooth). They bond chemically to the enamel, restoring the tooth's strength. They require less drilling/removal of healthy tooth.
- Cons: Typically more expensive. They may wear out sooner (7-10 years) than metal, though materials are improving every year.
The Verdict
For front teeth or visible areas, composite is the clear winner. For back molars with heavy chewing loads, silver is still a viable, durable option, though many patients now choose composite for all teeth to avoid the metal look.
