A composite (tooth colored) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth is removed and then filled with a composite filling. Composites set by curing it with blue UV light.
Composites are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
Composite fillings are available in different shades to match the color of the teeth as closely as possible. Hence they provide a very good aesthetics.
They stick to the tooth and hence need minimal cavity preparation. They can easily be repaired.
They are also used as a preventive measure in children in the form of preventive resin restorations and pit and fissure sealants. Also they can be used to restore the anterior tooth by veneer.
