Composites (White Fillings)

Composites (White Fillings)

Composites are composed of microscopic quartz filler particles in a resin matrix. They were first developed around 30 years ago but the early materials had numerous problems. Rapid improvements have been achieved in the last 10 years and the result is strength and durability similar to that achieved with amalgam.

The Choice is Black or White

amalgam fillings composites or white fillings

Advantages of Composite:
  • Same colour as the tooth.
  • Less cutting of the tooth is required so remaining tooth is stronger.
  • Strong adhesion irrespective of the shape of the cavity once the decay has been removed.
  • Strong bonding to the enamel, the composite is bonded so strongly that the enamel would be more likely to break away from the underlying dentine than the filling.
  • Reduces the chance of the tooth breaking. When the filling sets it contracts pulling the walls of the tooth together.
  • Can eat on it immediately. Composites are at full strength as soon as the curing light is removed.

Disadvantages of Composite:
  • Technique sensitive, badly placed composites will fail sooner
  • Placement is a longer procedure
  • Generally more expensive than amalgam
