A filling is a material the dentist will put onto or into your teeth to restore a hole or restore a tooth to its normal shape.

There are three basic materials used for fillings. The two white options are composite and glass ionomer and the silver option is called amalgam. At The Kensington Dentist we chose not to use amalgam.

Why would someone need a filling?

  • To restore tooth decay. Once tooth decay has broken through the enamel into dentine or you are experiencing symptoms such as pain, you will need to have a filling.
  • To restore tooth wear. Whatever the cause of loss of tooth structure is the role of a filling is to offer a protective layer to seal the exposed dentine as it is more susceptible to tooth decay, to avoid plaque build-up on uneven surfaces and reduce any sensitivity.
  • To restore a chipped/broken tooth. If you have chipped or broken a tooth, tooth coloured materials are applied to the tooth’s surface, hand crafted and sculpted into shape, hardened, and then polished for the ultimate natural appearance.

To replace an existing filling that has failed either because it got worn, fractured, debonded or decay grew around the margin as well as the possibility of its appearance no longer being aesthetically acceptable.

Clinical Procedure:

This depends on the reason for prescribing the treatment, in some instances there is no need for drilling or preparation of your tooth, the need for local anaesthesia may also be eliminated.

Your dentist selects the shade of composite that matches your tooth. The tooth surface will be etched with an acid gel then coated with a liquid that allows the tooth coloured resin to bond to your tooth. The composite resin is then sculpted, shaped and hardened with a special light. The material will be further trimmed and shaped. Once this has been completed, meticulous polishing will be undertaken.

The procedure is normally completed during a single visit of 30-60 minutes; however this may be longer or involve multiple visits depending on the extent, complexity and number of restorations you require. We only use high quality, h4, reliable and aesthetic composites.
