Amalgam Replacement | Amalgam Removal Brisbane

“A simple way to obtain natural looking dental aesthetics is to remove the amalgam fillings in your teeth and replace them with white fillings, such as composite resin fillings.”

Did you know that dental amalgam (also known as a silver filling) does not actually bond directly to your teeth?

A strong and robust dental material, many of you will be surprised to learn that despite its internal strength, amalgam fillings are actually held in place by their size and shape.

This means that rather than using bonding agents or etching techniques that hold newer fillings in place, some of your surrounding tooth must be removed and a niche carved out for an amalgam filling to be retained.

In some cases, old amalgam fillings may need to be replaced (left), particularly if they are leaking.
Replacement fillings (shown right) are available in a range of tooth coloured & biomimetic materials.



Due to innovations in modern dentistry, such as porcelain fillings, our patients frequently ask about amalgam replacement, and these newer fillings have several key benefits over amalgam, particularly for patients –

  • That wish to improve their dental aesthetics.
  • That would like to replace a cracked, leaking or failing filling.
  • Who are concerned about amalgam allergy.
  • Who are considering white fillings, porcelain fillings or composite fillings.
  • Who would like to reinforce teeth, and prevent cracked teeth and tooth cusps from fracturing.

Do you know if you have any leaky fillings?

Over time, the lack of bonding between an amalgam filling and the surrounding tooth can lead to a ‘leaky filling‘.

A leaky filling is one that has lost its initial fit and is unable to seal the cavity properly. In some cases, decay may creep into gaps behind the silver filling itself, and this can put the surrounding healthy tooth structure in jeopardy.

Every day use of your teeth, such as chewing, involves a series of small movements and high impacts. Due to this constant use, any filling material inevitably loses some of its structural integrity over time and your tooth is free to break away from the filling.

Replacing Your Amalgam Fillings with White Fillings

One of the greatest improvements in modern dentistry is the availability of materials with far superior aesthetic properties than their older counterparts. Newer materials, such as those used in porcelain and composite resin fillings, are ideal for matching the colour of your surrounding teeth.

Dr Tuffley says, “A simple way to obtain natural looking dental aesthetics is to remove the amalgam fillings in your teeth and replace them with tooth coloured fillings, such as composite resin fillings.”

Not only does this look good, but these materials bond to tooth surface and allow preparation and restoration with minimal impact on your surrounding tooth structure.

“Using these materials and techniques your existing fillings can be replaced without any structural damage to your teeth. Often these replacements have a higher inherent strength because unlike amalgam their chemical and physical characteristics allow them to bond to the walls of the tooth.”

Health Reasons to Remove Amalgam Fillings

Health reasons for amalgam removal exist, and research and clinical evidence shows that some patients can even be allergic to dental amalgam. If you are concerned about this, our team can test for the presence of this allergy in you or your family.

From a clinical perspective, it is important to acknowledge that amalgam fillings are not necessarily detrimental to your well-being, and that not every amalgam filling will fail at the same rate. This is because every tooth in your mouth has different contours, bite zones and shapes – and all these differences need to be taken into account when deciding whether a filling replacement will improve the aesthetics and strength of each tooth.

This means that any filling you are concerned about should be individually examined by your dentist before deciding on amalgam replacement or removal.

“Replacement for each of your amalgam fillings should be considered separately, unless complete replacement aligns with a larger treatment plan, an undiscovered allergy or your desired aesthetics,” Dr Tuffley says.
