Fillings – Amalgam Free Practice Townsville


Teeth can wear down, break due to trauma or get decayed due to bacterial caries. Dental fillings are used to replace and restore the form, function and aesthetics of missing tooth structure.  It is important to remember that regular cleaning of teeth can protect them from getting decayed. Regular dental check-ups are important to make early diagnosis and prevent deep fillings that can potentially need a root canal treatment or even lead to tooth loss. HEALTH PRECINCT IS AN AMALGAM FREE PRACTICE and we DO NOT USE ANY FILLING MATERIALS THAT CONTAIN MERCURY/ LEAD.

Here at Health Precinct, your teeth will be closely examined for caries before a decision is made to fill it. Advances in dental technology and latest materials offer newer horizons in creating a natural looking dental restoration. Advanced ceramic and Composite materials are made to mimic your natural tooth colour and shade giving you a confident smile.

Composite material is a modified plastic that is white and has shades that can match with human teeth. If your tooth needs a small filling, composite is the material of choice as there is minimal need to grind off the natural tooth structure. Composite has a unique ability to bind to your tooth making it an adhesive restoration.

Once we mutually decide to do composite restorations, your jaws would be numbed with a local anaesthetics. Bacterial caries and unsupported enamel would be removed with special hand pieces. SIROInspect is used to confirm complete removal of the bacterial decay. The tooth then needs isolation from moisture and saliva to achieve optimum adhesion bond strength. Nerves of the tooth may be protected with a base material. Special gel is used to chemically treat the tooth surface to improve adhesion. Filling material is built in instalments and hardened by exposing to blue light. The filling is then shaped and bite adjusted. Final polishing gives a lustre that makes a composite restoration appear near natural.

It is the inherent physical property of composite to shrink while getting hard, causing some stress concentration in the restoration. This makes some patients experience immediate post-operative sensitivity with composite restorations that usually lasts for 7-10 days. Any prolonged discomfort/ soreness or sensitivity has to be reported back. We, at Health Precinct take pride in the work we do and aim to deliver to you fillings that look and feel natural.

Composites are known to last for quite a few years if well maintained. However, scientific studies show bond strength deterioration in 3-5 years’ time causing composites to leak and discolour. Such failing composites, even though is intact in the tooth might encourage bacterial growth in the leaky areas causing secondary decay and eventual tooth loss. Regular check-ups and diagnostic radiographs help us maintain restorations and replace failing ones.

When a large part of tooth that involves cusps/ marginal ridges/ other structural parts of tooth is damaged due to trauma/ decay/ large restoration, we discuss with you, a stronger restorative materials made of ceramic. Dental ceramics are claimed to be the most biocompatible materials used to date for dental restorations and also the most natural appearing synthetic replacement material for the missing tooth substance with patient acceptance is high.

Since the 1980s, patient demand for highly aesthetic restorations, problems in the use of resin  composites for large restorations in posterior teeth, concerns about possible side effects and environmental effects of dental amalgam and recent developments in dental materials science have all led to interest in all-ceramic restorations. Ceramic inlays are made in the lab making them tough and a strong filling option.

Advantages of ceramic restorations are:

  1. They are tough and lasts long
  2. There is no marginal deterioration over time
  3. Ceramic restorations do not discolour
  4. Chances of secondary decay is low
  5. Ideal material of choice for a smile make over as they look exactly like natural tooth.
  6. Unlike Composites, there is no shrinkage in the material while hardening. So, structurally more stable.

Ceramic restoration are dearer compared to the composite options, but are known to protect teeth and last a lot longer. Ceramics being hard and brittle, have a risk of fracturing in case of extremely heavy force. Lastly, ceramics are stronger than natural tooth, making the opposing natural tooth wear over time.

All Inlay/ Onlays demand 2 appointments for completion of treatment. In the first appointment, after a clinical examination and all investigations, we will discuss the pros and cons of opting for  a ceramic restoration to protect your tooth. Tooth will be numbed with local anaesthesia and caries/ unsupported tooth structure removed. SIROInspect will be used to confirm complete removal of decay. The cavity will then be shaped with definite margins. Here at Health Precinct, we use a state-of-the-art 3D scanner to make digital impression of the prepared tooth that gets sent over to an Australian Dental Lab for fabrication. A temporary restoration will protect your tooth while the lab fabricates your permanent restoration.


Once the lab work arrives, your second appointment will be organised. On this appointment, your ceramic restoration will be tried for fit, colour matched and bite checked. If you feel good with the restoration and consent, the ceramic restoration will be secured with dental cement, adjusted accordingly and polished.

With paradigm shift towards aesthetic restorative options in dentistry, Composites and Ceramics have been popularised by modern dentists over Gold restorations. Gold dental fillings are ‘Ever-green Gold standard’, as no material satisfies the requirements of an ideal restoration as Gold, except for its appearance.  However, Gold restorations, being a non-tooth coloured material, is usually not objectionable, especially on back teeth that does not get displayed as you speak or smile.

Advantages of Gold restorations:

  1. Never break as Gold is malleable
  2. Excellent marginal integrity even after many years as Gold adapts continuously
  3. Co-efficient of thermal expansion similar to tooth, avoiding leak and secondary decay.
  4. Gold can provide precise and stable anatomic form. Wear of Gold and tooth is similar making a gold  tooth friendly material.
  5. Gold does not oxidise in mouth
  6. Gold is known to be bio-compactible.
  7. There is no Mercury in Gold fillings.
  8. Gold does not release any toxins in your mouth
  9. Gold castings are almost permanent restorations and are known to last for a very long time if well maintained, sometimes, for life.

Gold restorations, being dearer than composites, still have a low cost: benefit ratio considering its advantages and longitivity.
