What are composite fillings?

 

Composite fillings are strong, but may not be as hard wearing as amalgam fillings. Composite fillings are tooth coloured and are made from powdered glass quartz, silica or other ceramic particles added to a resin base. After the tooth is prepared, the filling is bonded onto the area and a light shone onto it to set it. The dentist will choose a shade to match your own teeth, although over time staining can happen.

What are glass ionomer fillings?

 

Glass ionomer fillings form a chemical link with the tooth. They may also release fluoride, which helps to prevent further tooth decay. This type of filling is fairly weak. Because of this, they are usually only used on baby teeth and ‘non-biting' surfaces such as around the ‘necks' of the teeth. Little preparation is needed as the filling bonds directly to the tooth.

What are porcelain inlays?

 

Porcelain inlays are also  made in a laboratory and this will need at least two visits to your dentist. Porcelain can be hard wearing and long lasting. It can also be coloured to match your natural tooth. Again, this type of filling can be quite expensive.
