In the past, the options for filling cavities were limited to the use of amalgam forms or inserts. Millions of Australians have had their cavities inserted with amalgam fillings despite the fact that they contain mercury. For the longest time, these metallic objects were tolerated because there were no better alternatives. The other reason is a lack of information in those days about potential mercury leakage from dental amalgam.
Thanks to the advent of modern substitutes like porcelain and composite resins, today’s patients no longer need to put up with amalgam.

What’s wrong with Amalgams?
One of the issues with amalgam being used in a tooth filling has to do with its propensity to movement when exposed to temperature changes. Exposed to intense temperature changes – i.e. eating hot/cold foods and beverages – the metal component would shrink or expand, thus causing damage to the tooth in which it was inserted.
Another problem with temperature changes on metals is that they cause the amalgam fillings to be in a constant state of flux, gradually weakening the metallic insert and making it vulnerable to bacterial infection, decays and cavities. Constant movement of the fillings over time can weaken the organic structure of the tooth.
As such, patients with metal fillings may find themselves in dental predicaments – having cavities or root canal problems – without even realising the cause to be the amalgam fillings in their mouth.
And then there’s the whole controversy surrounding the mercury…
Unfortunately, Mercury is known as one of the most harmful metals in existence. Even worse, the deadliest form of the metal is in its gaseous state.
It doesn’t help that the fear of silver colored amalgam fillings is due to its emission of toxic mercury vapors into the mouth on a daily basis. These fillings also break down during grinding, releasing dust vapors that get swallowed or absorbed. Mercury vapour has no distinctive smell thus can be easily inhaled without us ever noticing. Meanwhile, research carried out by the World Health Organization has linked amalgam fillings to the bulk of mercury found in human bodies.
Although the amount of exposure from dental amalgam is low, these fillings are often left in the mouth for many years raising the concern over potential long-term mercury exposure.
Mercury is linked to a host of health problems, including kidney, immune system and neurological damage. Mercury vapours, metabolized into methyl mercury can pose a significant threat to the human body by inhibiting our cellular ability to create energy and perform vital bodily functions.
Should I remove my amalgam fillings?
Millions of old amalgam fillings are removed every year, mainly due to fracture, wear and tear as well as concerns about exposure to mercury.
As an Amalgam-Free Practice, we offer safe amalgam fillings removal. Adopting special tools and processes to ensure minimal mercury release during the procedure, we make every effort to ensure that your comfort, safety and hygiene are being optimized throughout the procedure.
Further, we use high quality, modern porcelain and composite resin materials that possess high strength and resistance to fracture and wear and tear. Of course, these robust materials are also known for their natural aesthetics and tooth-like characteristics, allowing them to blend seamlessly with your natural teeth.
At Molonglo Dental Surgery, we encourage our patients to undergo a safe amalgam removal for replacement with white composite alternatives. This simple replacement process will give you a more natural looking smile and a mercury-free body.

Frequently Asked Questions
It’s a modern approach to dental care that completely avoids the use of traditional amalgam fillings. The dental amalgam is a traditional type of silver-coloured dental fillings that compose of metals, blended with mercury making up about 50% of the mixture. At Molonglo Dental Surgery, we use aesthetically-pleasing, tooth-coloured materials such as composite resin or durable ceramics. These dental filling alternatives are not only safer – because they do away with the mercury component – they also provide a much more natural and aesthetically pleasing result. The tooth-coloured modern dental filling alternative seamlessly blends with your own teeth for a smile you can be confident in showing to everyone.
The technology behind composite resins has come a long way. At Molonglo Dental Surgery, use what are known as nano-hybrid composites. Engineered for incredible strength and wear resistance, they bond directly to the tooth structure, which actually helps to reinforce its structural integrity. The perfect choice for small to moderate cavities, composite fillings are designed to be robust and durable for specific use cases. That said, in cases involving very large restorations or teeth that endure extreme grinding forces, a ceramic crown or onlay might still be the most suitable long-term solution. We’ll always discuss the best option for your specific needs.
It is completely safe to remove your old amalgam fillings. The primary concern for safe amalgam removal is the potential release of mercury vapour. At Molonglo Dental Surgery, we adhere to strict safety standards, which includes the following time-tested protocols: Use of rubber dam around the tooth to isolate it from the rest of your mouth; use of specialised high-volume suction to capture vapour and particles immediately; and running medical-grade air purifiers in the room to ensure the air you breathe remains clean and safe.
Most health funds with extras cover will provide a benefit for composite fillings on the front teeth, as they are considered a basic cosmetic restoration. However, health fund coverage for back (posterior) teeth vary between insurance providers and levels of cover. The item numbers are often different and attract a lower rebate. If you are unsure about your health fund coverage, you may drop by with your fund details. We can provide you with a detailed quote and check your exact rebate before we begin any treatment.
With proper care, a high-quality composite filling can last anywhere from 5 to 10 years, and often even longer. Their longevity is closely tied to excellent oral hygiene and regular check-ups.
There is a slight difference in cost. That's mostly due to three reasons: More expensive materials; meticulous placement process; more time-consuming procedure. However, the cost is significantly outweighed by the health benefits: Avoiding mercury; superior aesthetic outcome; and the positive environmental impact of not using mercury. To most patients, the small additional cost is well worth it. To make this choice accessible, we also offer a range of flexible payment plans.
While regulatory bodies state that the amount of mercury released from intact fillings is minimal and does not pose a significant health risk for the general population, some patients prefer to err on the side of caution. This may also be of greater concern for those with specific allergies, kidney issues, or those who are pregnant and breastfeeding.
