  • It has been used as a ‘filling’ material for over 150 years

Safety concerns

  • Mercury is also found in foods, soils and water
  • Mercury vapors can be released in small amounts from a dental filling and inhaled or absorbed into the body

Why is Amalgam still used?

  • It is a strong filling material
  • lasts a long time 
  • Does not break as easily as other materials
  • Mercury poisoning accumulates over time
  • No clinical research link between amalgam restorations and mercury poisoning has been found
