The Differences Between Amalgam and Composite Fillings

For years, dentists have been using amalgam fillings to protect teeth from decay. Made from a combination of metals, including mercury, amalgam fillings are considered safe and effective, and many dentists the world over still use them for restorations.

But a new type of filling is quickly becoming the preferred choice for many dentists, including Dr. Canzoneri—composite fillings. With composite fillings, Dr. Canzoneri can offer patients of our Arcadia office better protection from bacteria and plaque, protection that also matches a patient’s natural tooth color, resulting in a stronger, more esthetically pleasing smile.

What Makes Composite Fillings So Much More Resilient?

The reason largely has to do with the type of bond that exists between your teeth and your fillings. Composite fillings won’t change shape over time. Instead, they remain supportive of your tooth structure and continue to strengthen teeth by protecting against decay.

Amalgams, on the other hand, merely act as a barrier to plaque and bacteria. But as time passes, chewing can cause amalgam fillings to change shape and become worn down. Tiny cracks may even form, allowing for bacterial reinvasion and further complications.

Amalgams also require dentists to remove more of your natural tooth structure. But with composite fillings, Dr. Canzoneri can leave more of your tooth’s natural structure in place.

Enjoy a Stronger, More Natural-Looking Smile

But the biggest benefit for patients to consider is that composite fillings can be shaded to match the rest of your smile. Amalgam fillings are made of a mixture of metals, causing them to stand out against naturally white teeth. This can make patients feels self conscious about smiling or laughing. But with tooth-colored composite fillings, patients can enjoy a smile that looks confident and naturally white.
