There are many different filling materials to choose from but the most widely used and known are resin (white) and amalgam (silver). Dr. Worsley can discuss the advantages of both of them for your particular scenario, although resin is most commonly used and preferred by patients.


The advantage of resin fillings is their bonding which supports the remaining tooth structure, which helps prevent breakage and damage to your tooth. They are blended to match your natural tooth colour. These fillings are often used to improve the appearance of misshapen, chipped or discoloured teeth.

Composite resin fillings last about six to twelve years or more, and the procedure usually takes just one visit to your dentist. Less tooth is required to be drilled away to accommodate the mechanical requirements needed for a resin filling to be strong.

The disadavantage of resin fillings is that they can require more time to apply than amalgam fillings. This results in an increased cost. As they age, the resin shrinks away from the tooth causing the chance of bacteria to leak under the filling and need replacement.


The advantage of amalgam fillings is that they are marginally less expensive and will tend to last longer to direct chewing load.

The disadavantage of amalgam fillings is that they expand when they age and may contribute to parts of the remaining enamel to crack off. They also require a certain amount of drilling in order to stay in your tooth. They do not bond, they just stay put if shaped correctly. Their safety concerns over the absorption of elemental mercury contributing to several diseases, including Alzheimer's, multiple sclerosis, dementia and arthritis is often talked about. The FDA investigations have not proven that the minute amount of mercury vapors released from silver fillings is a health hazard. Amalgam fillings are a mixture of mercury liquid and small pieces of silver and other metals such as copper, tin and zinc.
