What You'll Learn
Mercury fillings are not banned in Australia
Mercury fillings, also known as dental amalgam, are not banned in Australia. Amalgam fillings are composed of about 50% mercury, with the remainder consisting of a mixture of silver, tin, and copper. While some countries like Norway, Sweden, and Denmark have banned their use, Australia has not followed suit.
In Australia, the National Health and Medical Research Council (NHMRC) acknowledges the uncertainty surrounding the health effects of mercury. The NHMRC recommends avoiding its use in children and pregnant women and suggests using alternatives to amalgam whenever possible. However, the Australian Dental Association has not imposed a ban on mercury fillings.
The debate surrounding dental amalgam centres on its safety. Proponents of amalgam fillings argue that it is safe, durable, relatively inexpensive, and easy to use. They contend that amalgam is a long-lasting solution that is tolerant of saliva or blood contamination during placement. On the other hand, critics assert that amalgam fillings may lead to mercury poisoning and other toxicity issues. They highlight the release of low levels of mercury vapour during placement or removal, raising concerns about potential health risks.
While Australia has not banned mercury fillings, it has taken steps to regulate mercury and mercury-containing products. In March 2022, Australia amended its laws to prohibit the import and export of elemental mercury. This amendment also included a ban on certain products containing mercury, such as batteries, switches, relays, and compact fluorescent lamps. Additionally, Australia has addressed the presence of mercury in vaccines and cosmetics, with only two remaining vaccines containing thiomersal and restrictions on cosmetics with mercury content above 1ppm.
In summary, while mercury fillings have not been banned in Australia, the country has implemented measures to control and reduce the use of mercury in various products, including dental amalgam. The NHMRC's recommendations reflect the cautious approach taken by Australia in addressing the potential health risks associated with mercury exposure.

The NHMRC recommends avoiding mercury fillings for children and pregnant women
Mercury fillings, also known as dental amalgam, are a combination of mercury, silver, tin, and copper. They are considered safe and effective in countries practicing modern dentistry, with supporters touting their safety, durability, affordability, and ease of use. However, critics argue that amalgam fillings may lead to mercury poisoning and other toxicity issues.
In Australia, the National Health and Medical Research Council (NHMRC) acknowledges the uncertainty surrounding the health effects of mercury. As a result, the NHMRC recommends avoiding mercury fillings, especially for children and pregnant women. This recommendation is based on the potential risks associated with mercury exposure and the availability of alternative filling options.
The NHMRC's position aligns with international efforts to reduce mercury use. Countries like Norway, Sweden, and Denmark have banned or restricted dental amalgam, prioritizing environmental concerns and public health. Additionally, the EU Mercury Regulation prohibits mercury fillings for children under 15 and pregnant or breastfeeding women, with a complete ban for all patients planned for 2025.
While Australia has not implemented a complete ban on mercury fillings, it has taken steps to reduce mercury usage. In March 2022, Australia amended its laws to prohibit the import and export of elemental mercury and certain mercury-containing products, such as batteries and compact fluorescent lamps. These changes demonstrate Australia's commitment to fulfilling its obligations under the Minamata Convention.
It is important to note that the Australian Dental Association and similar organizations in other countries argue that dental amalgam is safe and has been used extensively in the past. They emphasize that current evidence does not indicate that dental amalgam is causing widespread illness, and a total ban is not justified. However, with growing concerns about mercury's potential health and environmental impacts, the NHMRC's recommendation to avoid mercury fillings, especially for vulnerable populations, is a cautious approach until further research provides more definitive conclusions.

Amalgam fillings are about 50% mercury
Mercury fillings, also known as amalgam fillings, are a combination of metals, including silver, tin, copper, and zinc. They are commonly used to fill cavities in teeth caused by decay. Amalgam fillings have been a subject of controversy due to their mercury content and comprise approximately 50% of the filling material. While some countries have banned or restricted their use, others continue to utilise them.
Amalgam fillings have been a topic of debate due to the potential health risks associated with mercury exposure. Mercury is a toxic substance that can have harmful effects on the human body. In the context of dental fillings, mercury is released in vapour form, which can be inhaled or ingested. This exposure to mercury vapour can occur during the placement or removal of fillings, as well as through everyday activities such as chewing, brushing, and consuming hot liquids.
The release of mercury vapour from amalgam fillings has raised concerns about its potential impact on health. Some individuals with amalgam fillings have reported health symptoms similar to those associated with Multiple Sclerosis (MS). Additionally, studies have shown a correlation between the number of amalgam fillings and mercury levels in the body, including blood, urine, and hair mercury levels. However, the specific health effects of mercury exposure from dental amalgam are still uncertain, with conflicting findings from various studies.
In recognition of the potential risks, some countries have taken steps to ban or restrict the use of amalgam fillings. Norway, Sweden, Denmark, and Russia have banned amalgam fillings, while other countries like Japan, Italy, Spain, Finland, Germany, and Austria have implemented restrictions. These decisions are often informed by international organisations and their assessments of the health effects of mercury.
In Australia, the National Health and Medical Research Council (NHMRC) has acknowledged the uncertainty surrounding the health effects of mercury. As a result, the NHMRC recommends avoiding the use of amalgam fillings in children and pregnant women and encourages the use of alternative filling materials whenever possible. While Australia has not implemented a complete ban on amalgam fillings, the percentage of amalgam fillings placed has been decreasing over the years.
It is worth noting that amalgam fillings have certain advantages, such as their strength, durability, and affordability. However, due to the potential health concerns associated with mercury exposure, the decision to use amalgam fillings should be carefully considered in consultation with a dental professional.

Mercury is banned in batteries, cosmetics, and some medical devices in Australia
Australia has amended its laws to prohibit the import and export of elemental mercury, also known as metallic mercury, as of March 7, 2022. This amendment is in line with the country's obligations under the Minamata Convention, a global environmental agreement aimed at protecting human health and the environment from the harmful effects of mercury.
Mercury is now banned in several products in Australia, including batteries, certain types of lamps and lighting, switches and relays, and cosmetics. Specifically, batteries with a mercury content of more than 2% are banned, except for specific types of button cell batteries. Compact fluorescent lamps (CFLs) for general lighting purposes with a mercury content exceeding 5mg per lamp burner are also prohibited.
In the cosmetics sector, Australia has banned products with a mercury content above 1ppm, including skin-lightening soaps and creams. However, this ban does not extend to eye area cosmetics where mercury is used as a preservative and no effective and safe substitute preservatives are available.
Additionally, Australia has undertaken a post-market review of medical devices listed in the Australian Register of Therapeutic Goods (ARTG) that may contain mercury. This includes non-electronic blood pressure monitors, sphygmomanometers, thermometers, and plethysmographs (used to measure lung capacity). All mercury-containing devices included in this review have been cancelled from the ARTG, meaning they can no longer be supplied in Australia.
