TreatmentsFillings

Filings (dental restorations) are one of the most common procedures that we undertake.

These direct restorations can be as simple as a single surface filling or as complex as cosmetic overhaul of your front teeth.

There are a variety of direct filling materials available and we will discuss with you the options that will best suit your particular cavity. Almost all of the restorations we place are with tooth-coloured materials. However, there may be certain circumstances where these materials are inadequate. Prior to the placement of any filling we will discuss the positive and negative aspects of the materials we can use.

Amalgam fillings have been used effectively in dentistry for decades. Many people have concerns over their safety and appearance. Dental amalgam is an alloy of silver, tin, copper and mercury.

We find that patients commonly ask us if they should have their amalgam fillings replaced. Our answer to this question depends on the reasons behind the request. We will always listen to your questions and concerns before providing you with all the information you need to make an informed treatment decision.

Understandably aesthetics is a key reason for many people requesting replacement of their silver fillings. In these instances we will generally be able to supply you with a treatment plan to achieve the desired result.

People are also concerned about the safety of their silver fillings. Current research indicates that dental amalgam is still safe to use intra orally in adults. Replacing fillings that are sound may create problems that otherwise may not have occurred. These can include damage to the remaining tooth structure and sensitivity or pain.

There are a number of reasons why a filling may need to be replaced. This can include new decay, breakage or aesthetics. In most instances it will be possible to replace the defective restoration with a tooth coloured filling.

The National Health and Medical Research Council (NHMRC) advises that:

… general public and environmental health principles dictates that where possible exposure to mercury from dental amalgams be reduced where a safe practical alternative exists. This becomes more prudent in special populations, including children, women in pregnancy and persons with existing kidney disease.

For those patients requiring the removal of previous amalgam restorations, it is possible to reduce their exposure to the mercury by placing rubber dam over the treated teeth.
