Fillings

Filling TrayTooth Coloured Fillings

Tooth coloured fillings are made from tooth coloured materials that restore the natural appearance of a decayed or previously filled tooth.

Composite Fillings

Composite fillings are made of plastic material mixed with small glass particles and are tooth coloured, rather than silver. They are suitable for repairing both the front and back teeth. After preparing the tooth, your dentist will place layers of the composite filling into the area to be repaired. Each layer of the composite material is hardened by exposure to a special light. Once the cavity or defect is filled, your dentist can trim the composite to fit the tooth and then polish it to reduce discolouration or staining.

Advantages of Composite Fillings:

  • Composite fillings are more attractive than amalgam fillings.
  • Teeth filled with composite material tend to be stronger, as it bonds to the surrounding tooth, while a tooth filled with amalgam may be sometimes weaker.
  • Composite fillings can be fitted into very small holes, so less drilling is needed in preparation for fillings.

Inlays

Inlays are fillings that were traditionally made of gold but now are often made of porcelain, ceramic or composite material. They are used to repair moderately damaged back teeth and need to be extremely strong to withstand the grinding pressures of these teeth.

Inlays are glued into place and are contained within the cusp tips of the tooth. Special glue is used to increase the strength of the bond.

Porcelain inlays are popular because they resemble your natural tooth. A porcelain inlay is made by a professional dental laboratory and is permanently cemented into the tooth by your dentist.

Onlays

Onlays are essentially identical to inlays with the exception that one or more chewing cusps have also been affected and need to be included in the restoration. An onlay is much stronger than any other type of filling and actually increases the strength of the tooth.
