A composite resin is a tooth-coloured dense plastic mixture filled with glass (silicon dioxide) first introduced in the 1960s.
When expertly handled they have proved to be long lasting filling materials.
Composite fillings are more difficult to place than silver fillings so may take your dentist longer to complete.
As they are considered to be a cosmetic filling, they are not available on the NHS.
The main advantage of composite fillings is their aesthetic appeal.
The life expectancy of your composite filling can depend on the depth of the cavity and its position in the mouth.
Very large restorations are best treated by the CEREC method, or ceramic inlays and onlays. Your dentist is best positioned to advise you.
