Composite Fillings Procedure

What is the Procedure for Composite Resin Fillings?

  1. The dentist prepares an access to the decayed area of the tooth and removes the decayed portion which is normally accomplished with traditional drills, air abrasion or even with a dental laser.
  2. Once the decay is removed an etchant is applied for 15-20 secs.Etchant opens up the pores of your tooth’s dentin and roughens up the surface of exposed enamel. This is done to achieve a stronger bond.
  3. After the tooth is etched, the acid is rinsed with a stream of water for 20 sec and enamel is dried.
  4. After that bonding agent is applied so that the composite filling sticks to the tooth. The material is made of the same resin as composite resin but is more fluid in consistency. The layer is then hardened and cured with visible light.
  5. Composite Resins are applied in increments and slowly built to form the complete filling.
  6. Once the filling is completed, the bite is checked with an articulating paper and adjusted and the tooth is then polished with a polishing kit. Finally, a layer of bonding agent is applied which helps to seal the marginal gap.

 Pros and Cons of Composites

Advantages:

  • Better Aesthetics as they match to your natural tooth colour.
  • More conservative is less drilling is required compared to the amalgam fillings.
  • Less sensitivity to hot or cold items in comparison to amalgam.

Disadvantages:

  • Cost for placing the composite filling is more.
  • Time taken to apply composite filling is more as compared to amalgam fillings.
