What is Composite Restoration/Filling?

A Composite Filling is a tooth-colored plastic and glass mixture used to restore decayed/carious teeth. Composites are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.

Procedures of Composite Restoration/Filling:

Dental composites can be used for:

  • Filling cavity of carious/decayed teeth.
  • Filling cavity preparations.
  • Filling gaps (Diastema) between teeth.
  • Minor reshaping of teeth.
  • Partial crowns on single teeth.

Advantages of Composite:

  1. Composite fillings can be closely matched to the color of existing teeth.
  2. Composite micro-mechanically bonds to tooth structure. This strengthens the tooth’s structure and restores its original physical integrity.
  3. Less healthy tooth needs to be removed for a composite restoration procedure.
  4. Less-costly and more conservative alternative to Dental Crowns.
  5. Composite fillings can be used to repair chipped, broken or worn teeth.
  6. Minor damage to a composite filling can be repaired by adding additional composite.
  7. Reduced mercury exposure for both patient and dentist.
  8. Composite Restoration does not corrode.

Disadvantages of Composite:

  1. Composite shrinkage might cause secondary caries. 
  2. Composite fillings may not last as long as Amalgam fillings under the pressure of chewing.
  3. Composite can chip off the tooth.

Composite Fillings/Restorations must be placed by Qualified Dentists or Dental Specialists. If you are in doubt, always consult your Dentists for further clarification. If you find this article useful, feel free to share it with your family and friends.
