Modern dental care offers numerous filling materials for cavities. One common type is an amalgam, which consists of liquid mercury and powdered metal alloys. Also described as a silver filling, it has been used as a restorative material for 150 years. If your child needs treatment to address cavities, here's what to know about this option.

A Guide to Dental Amalgams

Are they safe? 

Since dental amalgams contain mercury, there have been concerns about their safety. At room temperature, this liquid emits a vapor that can potentially cause brain and kidney damage when inhaled in large amounts. 

However, the amount of vapor released during the application of a dental amalgam is low to mitigate these damage risks. There is no conclusive evidence linking a silver filling to adverse health effects, with most issues that develop being related to anxiety symptoms instead. 

Is there anyone who should not receive these fillings? 

While dental amalgams are safe, children under 6 years old and pregnant and nursing women should avoid them. This precaution is due to potential neurological damage in developing fetuses, babies, and young kids. 

However, more evidence is needed to prove this health problem occurs. In the meantime, patients at risk should still find an alternative option.

Are allergic reactions possible? 

The patient's body can negatively respond to a dental amalgam if they have a metal allergy. Common reactions to the mercury, copper, tin, or silver materials in fillings include oral lesions or sores. Discuss other alternatives with a pediatric dentist if you believe your child has a metal allergy. For instance, they can use composite resin, glass ionomer, or ceramic options instead.

What are the benefits? 

This dental care treatment option remains popular for its affordability, durability, and longevity. In contrast to other filling materials, it lasts up to 12 years and is unlikely to fracture and break. A dental amalgam is also easy to install in cavities, avoiding potential contamination caused by blood and saliva.
