Amalgam, the common silver substance utilized to fill cavities, has been utilized in dentistry for longer than 100 years. It is a mix of metals like silver, mercury, tin and copper and has traces of zinc, indium or palladium. Generally amalgams contain 50% of mercury 35% of silver and 9% tin and 6% of copper and traces of zinc as well as other metals. As alternatives there can be amalgams made with larger percentages of metals like copper or indium which can bind mercury strongly and may decrease its release from this mixture.
Mercury is used in amalgam since it helps make the material more pliable. It generates a compound that is soft enough to pack into the teeth but quickly hardens to face up to the actions of biting and chewing.
