Fillings

There are two types of filling materials which may be offered depending on the clinical scenario and your personal preference. Composite Resin (white) fillings or Amalgam (metal) fillings.

Although most people prefer the white fillings, it is our ethical responsibility to provide both options and explain the pros and cons of each. You will then be able to make an informed decision based on facts and scientific evidence.

 

Composite restorations, or white fillings, are resin based.

They have been routinely used since the 1950’s and are becoming more and more reliable in terms of bonding and strength.

Advantages:

• They are tooth coloured and ideal in aesthetically demanding situations.
• They bond to natural tooth.

Disadvantages:

• They are very technique sensitive, and should be done under rubber dam and in small increments.
• They may shrink and cause cracks in the tooth.
• They pick up stains from food and drinks over time. They can be polished to remove most stains.
• They wear quicker than amalgam and may need to be replaced.

Composite resin longevity has been documented to be about 7 years.

 

Amalgam restorations are those fillings made from metal, and have a grey/silver appearance.

They have been used for hundreds of years and are by far the most reliable in terms of strength and longevity.

Advantages:

• High in strength
• Wear slower and are more long lasting
Amalgam’s longevity has been documented to be about 10-15 years.

Disadvantages:
• They are metal looking and not aesthetically pleasing.
• Contain Mercury

The concern for many patients is the mercury which is found in the filling. However, we do not advocate the removal of amalgam unless for cosmetic reasons or in situations where active decay is present under the filling.

In such instances we practice removal of amalgam in the safest possible manner. This is done under rubber dam and with high volume suction.
