1. What is a composite restoration?

  • The composite restoration is named after material that is used, namely composite resin.
  • Composite resin is a plastic tooth-coloured material that is used as a filling. It is also called a white or plastic filling.
  • It is aesthetic and durable.

2. What is bonding?

  • The process of repairing a tooth with a composite filling is called bonding.
    • The composite material is placed into the cavity in layers until the tooth is restored to its original form.
    • The filling is permanently fused or bonded to the tooth.
    • This is a major advance for dentistry.
      There is no longer the need to cut a slot into a tooth to hold a filling in place, as is necessary for an amalgam filling.
      The preparation for an amalgam filling entails the removal of the decayed part and a small amount of healthy tooth.
      Less tooth needs to be cut away with bonding, as only the decayed part is cut out.
    • An ultraviolet light is used to harden it, and it can be chewed on immediately after it has been completed.
      It has this advantage over an amalgam filling which takes a few hours to harden.
  • We at Simplyteeth have named it “the superglue of dentistry”.

3. When is bonding of special use?

  • Bonding has all the qualities needed for cosmetic dentistry. This applies particularly to the repair of discoloured front teeth.
    • Chipped and fractured teeth can be aesthetically repaired as the examples below illustrate.
    • The spaces between teeth can be reduced or closed by applying the composite to the teeth on each side of the gap.
    • The visible surface of a front tooth can be “re-surfaced” with the use of composites. This will, however, be less durable than a porcelain veneer.
