Amalgam fillings have been a reliable option in dentistry for over a century, offering a strong and long-lasting solution to cavities. However, some patients today are concerned about the mercury in these fillings. As dentists, we discuss with patients whether they should replace their amalgam fillings with newer options like composite or ceramic. It's important to weigh the benefits and risks before making a decision. While mercury is a component of amalgam, it's often misunderstood. Many health organizations, including the FDA and ADA, still consider these fillings safe for most individuals.
When considering whether to remove amalgam fillings, it's crucial to weigh several factors, including your overall health, the condition of your existing fillings, and whether they are causing any problems. While amalgam fillings are composed of mercury, silver, tin, and copper, studies have shown that the levels of mercury released from these fillings are very low and are generally not harmful. Removing amalgam fillings unnecessarily can actually pose more risk than leaving them in place, as the removal process can expose you to more mercury vapor than simply leaving the fillings undisturbed.However, if your amalgam fillings are deteriorating or you have a documented allergy to mercury, removal may be the best option.
Understanding the Composition of Amalgam Fillings
Amalgam fillings are made from a mixture of metals, including mercury, which is what often raises concerns. However, it's important to understand that mercury in amalgam fillings is bound with other metals, making it stable. The small amount of mercury vapor that may be released when chewing or drinking hot beverages is considered too low to cause harm in most people. Multiple scientific studies have supported the safety of amalgam fillings, and many dental organizations continue to endorse their use, especially for larger cavities in molars where durability is important.
What Are the Risks of Amalgam Filling Removal?
Removing amalgam fillings involves drilling, which can release more mercury vapor into the air. In many cases, leaving well-functioning amalgam fillings in place is safer than removing them. If removal is necessary, we take precautions to minimize your exposure to mercury vapor during the procedure. These precautions include using high-speed suction, rubber dams to isolate the tooth, and air filtration systems. It's essential to discuss the potential risks and benefits with your dentist before making any decisions.
Alternative Materials For Fillings
If you do decide to replace your amalgam fillings, there are several alternatives available. Composite resin, porcelain, and gold are popular choices. Composite resin is tooth-colored and can be used for smaller fillings, while porcelain and gold offer durability for larger restorations. Each material has its own benefits and limitations, so it's essential to choose the one that best fits your needs based on the size and location of the filling and your aesthetic preferences.

Can I Replace My Amalgam Fillings With Composite?
Yes, you can replace your amalgam fillings with composite resin. Composite is a tooth-colored material that offers a more natural appearance.

If you're considering replacement for cosmetic reasons or because of damage to the existing filling, we can help you decide if composite is the right choice for you.
Is There A Health Risk Associated With Amalgam Fillings If I'm Pregnant?
While amalgam fillings are considered safe for most people, the FDA advises that pregnant women, nursing mothers, children under six, and people with pre-existing kidney conditions may want to avoid amalgam fillings due to potential risks from mercury exposure.
