Based on up-to-date scientific research, the IAOMT has developed rigorous recommendations for removing existing dental mercury amalgam fillings to assist in reducing the potential negative health outcomes of mercury exposure to patients, dental professionals, dental students, office staff, and others. The IAOMT’s recommendations are known as the Safe Mercury Amalgam Removal Technique (SMART). To learn more about the science behind SMART, choose from one of these two options.

Mercury vapour (Hg(0)): Continuing toxicological uncertainties, and establishing a Canadian reference exposure level

Policy and clinic decisions need a number: how much mercury vapor is too much for continuous inhalation? Richardson and colleagues reviewed toxicological uncertainties for elemental mercury vapor and derived a Canadian reference exposure level (REL).

Dental “silver” tooth fillings: a source of mercury exposure revealed by whole-body image scan and tissue analysis

Are amalgam fillings sealed tombs—or slow-release sources? Hahn and colleagues used radioactive mercury in animal amalgam restorations and whole-body imaging to visualize where released mercury goes.

Safe removal of amalgam fillings in dental clinic: use of synergic nasal filters (active carbon) and phytonaturals

Chewing, brushing, and hot drinks spike mercury from amalgam—safe removal protocols plus carbon nasal filters and phytonaturals cut exposure.

Longitudinal analysis of the association between removal of dental amalgam, urine mercury and 14 self-reported health symptoms

People with amalgam had double the urine mercury; after removal, levels fell and self-reported symptoms were more likely to improve.

Mercury vapour exposure during dental student training in amalgam removal

To maximize safety, dental schools should train students to remove amalgam only while using water spray and high volume suction. Alternatively, students should use appropriate occupational hygiene personal protective equipment during amalgam removals.
