Empowering our patients with knowledge to make informed decisions about their dental care is a core value we uphold. Amalgam fillings, often referred to as silver fillings, have been foundational in dentistry for over a century. This blog delves into the composition, benefits, and potential risks of amalgam fillings, providing you with the necessary insights to assess their appropriateness for your dental health.
What Are Amalgam Fillings?
Amalgam fillings are a durable mixture of metals including mercury, silver, tin, and copper. Mercury acts as a binder for the other metals, creating a hard, wear-resistant filling.
Potential Risks of Amalgam Fillings
Mercury Exposure: While stable, certain activities like teeth grinding can release mercury vapor.
Structural Impact on Teeth: Amalgam fillings require the removal of a significant amount of tooth structure, which can weaken the tooth.
Thermal Sensitivity: The metallic nature of amalgam means it reacts to hot and cold, which can cause discomfort.
Biocompatibility Concerns: There are potential allergies to the metals used in amalgam.
Benefits of Amalgam Fillings
Durability and Longevity: Amalgam is highly durable, often lasting longer than alternative materials.
Cost-Effectiveness: It remains one of the more affordable filling materials available.
Modern Viewpoints and Alternatives
Global trends are moving away from amalgam due to environmental concerns and the availability of advanced materials such as composite resins and ceramics, which offer improved aesthetics and require less tooth preparation.
When Removal is Warranted
Removal of amalgam fillings may be advised if there is evidence of structural failure or for cosmetic reasons. It's essential that removal is conducted using safe protocols to minimise mercury exposure, such as using a rubber dam and high-volume suction. It's best to speak to your dentist regarding the state of your amalgam fillings and whether they need to be removed.
