What’s the difference between mercury free and mercury fillings (and why Fox Point uses mercury free)?

Amalgam fillings revolutionized the treatment of tooth decay and cavities hundreds of years ago. 

Before fillings came to be, dental patients were at risk of losing teeth, yikes! And amalgam fillings consisting of mercury and a mixture of tin, copper, silver, or zinc were discovered to halt the spread of bacteria in the tooth. 

This approach saved so many people from losing teeth! However, modern research in dentistry has led to better, safer, more conservative techniques to treat cavities—like mercury-free bonded dentistry.

What Are Mercury Fillings?

These types of amalgam fillings are often referred to as “silver fillings” because they look silver – but this term doesn’t explain what they are correctly!

Dental amalgam (or silver filling) is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper. These fillings can contain up to 50% mercury. And mercury is a highly toxic element. In fact, there is no known safe level of mercury exposure.

Research shows that silver dental fillings expose you to the harmful effects of mercury. Some patients are extremely sensitive to mercury, and having amalgam fillings impact a patients’ health if they are sensitive to this element.

Why are we seeing mercury fillings commonly breaking teeth?

To place an amalgam filling, the dentist also has to remove a lot of tooth structure to get the filling to stay put…it’s held in by “undercuts” or little ledges cut out of your tooth.  It is a metal, and it acts like a wedge inside your tooth.  Over time, little cracks form in your tooth, all around the filling.  When a tooth cracks all the way, it normally will crack toward the nerve (hello root canal!) or down below the gums, and sometimes can’t be fixed!  

When we look at these fillings over time, many of them need to be replaced with crowns and more extensive dental work.

What Is Mercury Free?

“Mercury Free” refers to dentists who do not put silver amalgam fillings in their patients’ teeth. Great alternatives to amalgam fillings are composite resin, glass ionomer, porcelain, zirconia, and gold.
