Amalgam

Key Points

  • Dental amalgam is a safe, affordable and durable restorative material.
  • Although amalgam remains an effective and inexpensive restorative option, environmental concerns regarding mercury have fueled legislative and regulatory actions in other countries to phase down amalgam use.
  • Considerations of post-placement sensitivity, longevity, esthetics, conditions under which the restoration is to be placed, and cost may all be factors in choosing a restorative material.
