Fillings are placed where decay exists or an old filling needs replacement.

When you visit us at our clinics to get a filling:

  • You may be given local anaesthesia to numb the area if necessary.
  • Your dentist will start off using a high speed small drill or laser to cut through the unsupported enamel and remove the decay.
  • The drill will then reach the second layer of the tooth which is called ‘dentin’. This is where the dentist will switch to a low speed drill as dentin is much softer than enamel.
  • Upon completion of the removal of the decay, your dentist can now shape up the space to prepare it for the filling. A base or a liner to protect the tooth’s pulp will be added (close to the nerves) as this will provide further protection. This base can be made from different sorts of materials some of which consist of composite resin, zinc oxide, eugenol and glass ionomer. Some of these materials release fluoride to protect the tooth from further decay.

Remember, decay is not the only reason you may need a filling.

Other reasons include:

  • Cracked or broken teeth.
  • Teeth that are worn from unusual use, such as:
    • Nail-biting
    • Tooth grinding (bruxism) and
    • Using your teeth to open things... not at all recommended.

White Fillings

A White filling is a tooth-coloured plastic and glass combination which can be used to restore decayed teeth. Another name for white fillings is ‘Composite Resin’ which is known and used for cosmetic improvements of the smile by changing the colour of the teeth or reshaping disfigured teeth.

Our dentists at Chartwell/Rototuna clinics place the composite in layers and then we use a light which is designed to reinforce each layer. Once complete, the dentist will outline it to fit your tooth, finishing off with polish to preventing early staining and wear and tear.

White fillings are far more popular in this generation than the conventional silver fillings. They provide a more aesthetically pleasing smile and a stronger  bond to the tooth which can prevent the tooth from breaking and insulates it from excessive temperature change.
