Dental Restorations & Fillings

Fillings to Restore your teeth

Do you have teeth with dental cavities or old silver fillings that need to be replaced? Teeth that have been weakened by decay or cracks can be brought back to strength while also looking good with white restorations.


The Benefits Of Replacing Old Fillings

Old, unsightly fillings can break down over time or causing cracks and stains in the enamel of your teeth. Some people will have a cavity which is slowly developing and only visible in the mouth or on X-ray, without any symptoms at that stage. However there are also situations where people experience sensitivity due to decay which has progressed through a tooth.

Unfortunately, this decay and cracks only continue to progress without care and treatment. By waiting too long, the decay can affect the nerve and lead to irreversible damage and root canal treatment. The weakened enamel can fracture, leaving little remaining tooth structure to restore the tooth effectively. This can all be avoided by placing a restoration in time and to ensure that further complications and more expensive treatment are avoided.

What are my options?

White fillings are made of composite resin material and are placed in the dental surgery in one visit. They are a good choice for replacing small amounts of dental decay as they preserve your natural tooth structure and rebuild your tooth conservatively.

However, if you have larger amounts of decay, or cracks on teeth due to old amalgam fillings or general wear, a laboratory-crafted restoration is recommended. These filings are called inlays or onlays, and give the tooth a natural look while supporting the remaining enamel. An inlay is placed within the cusps of a tooth, whereas an onlay will replace one or several cusps of a tooth.

Inlays and onlays are constructed in a laboratory to precisely fit your tooth. They are bonded to your enamel resulting in no shrinkage of the material while strengthening your enamel. In comparison, the same large filling done in a composite resin material in the dental chair will always shrink a little during the setting process, leading to micro-spaces in which food, plaque and bacteria may enter, causing further problems.

Onlays are often a good choice for teeth which have broken down but do not require the full coverage of a crown. There is very little extra tooth preparation required to make space for inlays and onlays, making them a good conservative option to regain tooth function.

Do I need an inlay or onlay?

Many people are choosing to replace their old worn out silver fillings with inlays and onlays. When there is a significant amount of decay or damage already done to a tooth, a simple composite resin filing may not be the best option. By placing an inlay or onlay, the tooth is strengthened and the restoration will last without further damage to the good tooth structure.

Examples of these situations include:

  • Old large silver fillings
  • Teeth with cracks or stains
  • Teeth with large amounts of decay
  • Teeth that have lost a cusp or a large amount of tooth structure.


Each inlay or onlay requires two visits to complete. Once your old filling or decay is removed, a mould is taken from which our highly technical laboratory team crafts your inlay or onlay to mimic your natural tooth. Once Dr Berera is satisfied with the fit and accuracy of your restoration, and you are happy with the appearance, it is permanently bonded, resulting in a stronger, longer-lasting tooth.

As with all dental work, your home oral care routine along with regular dental maintenance appointments and cleans will ensure that your teeth and gums stay healthy and protect the longevity of your dental work.
