White Fillings

Thinking of replacing your old amalgam fillings? Contact Albany Dental at (07) 3264 9590 for a safe removal and better aesthetic option!

Even with regular brushing and flossing, cavities may still find their way into the nooks and crannies of your teeth. It is recommended that you make it a point to see your dentist at least twice a year, if only to keep your cavities in check – before they get a chance to destroy your tooth to the point that requires an extraction. The good news is, if the dentist detects the cavity at an early stage, it can be easily treated with a dental filling.

At Albany Dental, we recommend the more aesthetic looking and safer direct filling method and dental material. White Fillings, also known as Synthetic Resin or Composite Fillings, are the new generation material used by dentists to replace the old amalgam fillings.

White fillings have become the trusted filling material of choice for many dentists because they produce the most aesthetic results for the patient, while allowing the least invasive filling method. They are also widely considered to be the safest filling material around – as opposed to health concerns surrounding the use of metal fillings.

Don't give your cavity a chance to grow into a major dental defect. Schedule a routine check by Albany Dental at (07) 3264 9590. If a filling is required, rest assure that we will use the most effective yet aesthetic choice to treat your cavity problem.

Amalgam Fillings: The Old Standard

As the name suggests, dental fillings are used to fill the hole where the cavity was in order to stop tooth decay from spreading. Silver-coloured amalgam fillings were historically the material of choice. While durable and effective for all tooth surfaces, the amalgam filling is criticised for its unattractive appearance and controversial mercury composition.

Amalgam fillings are made from an alloy containing mercury, silver, copper and tin. Since about half the weight of amalgam fillings are attributed to mercury, there are concerns over its mercury exposure (although extremely low) as a potential health hazard.

Decay weakens a tooth. Amalgam fills the hole but doesn’t make the tooth strong again.

  • Amalgam is not glued, it is just wedged into the hole.
  • Amalgam expands and contacts 3 times more than tooth with a cold drink or hot food.
  • With time, the tooth around the amalgam starts to crack.
  • Moisture and germs get in under the filling because there is no glue.

The two major problems that result are:

  • Decay hits the nerve and the tooth needs root treatment
  • A large piece of valuable tooth breaks off or the tooth splits in half.

Don’t leave it till it is too late! Teeth that are filled with a lot of amalgam (More than 50% of the biting surface) Are better restored with ceramic.

White Composite Fillings: New generation material of choice

In recent years, composite fillings have become the preferred choice because they match the colour of natural teeth allowing for a cosmetic dental restoration. White fillings compose of glass, quartz and other materials mixed with a resin compound.

Thanks to advances in dental material science, the synthetic material can be customised to meet both your aesthetic as well as restorative needs. For example, the dentist can create a filling that precisely matches your particular tooth colour shade. The filling can also be moulded to fill the gap seamlessly, while giving the same shine and translucent quality!

By varying the composition of the fillings, the dentist may even appropriate a more durable form of fillings for your molars (for higher chewing loads) as opposed to a "less rugged" version for fillings near the gum line. With composite fillings, you'll get flexibility and beauty working for your restoration in perfect harmony! 

Minimal Tooth Reduction

One major drawback of amalgam fillings is that they are mechanically held in place. Part of the filling procedure requires dentists to place undercuts in the dental preparation that necessitates the removal of tooth structure. This can compromise the original robustness of the tooth and render it more susceptible to leakage and breakage.

Composite resin materials, also known as direct filling materials, are bonded to the tooth using a light curing method. The light source activates the material to generate a chemical reaction that bonds it directly to the tooth. Compared to amalgam fillings, this method allows for minimal tooth reduction so as to preserve the original strength and condition of the tooth.

Temperature Sensitivity

As amalgam fillings age, they tend to expand and contract when they come into contact with hot or cold foods and beverages. This can result in cracks and cause tooth fractures, loosening and even detachment. In the worst-case scenario, the cracks may extend to the nerve and result in a root canal or tooth extraction.

Made of plastic material, composite resins might also expand and contract when the temperature changes. However, this is commonly felt within the tooth resulting in tooth sensitivity that will likely go away after one to two weeks.

Overall, composite resin fillings are not as temperature sensitive as amalgam fillings and have been proven a consistent material of choice for many dentists.
