A filling is a dental restorative material used to restore the function and integrity of missing tooth structure, often from tooth decay or from external trauma. Fillings consist of a material used to restore the function and integrity of a missing tooth structure as a result of tooth decay, cracking or chipping. The factors considered are the extent of the damage and how much restoration is needed.

How do you know if you need a filling?

Only a dentist can assess whether you need a filling or not. During your dental assessment, your dentist will use a small mirror to perform an oral examination to examine at the surfaces of your teeth primarily. Your dentist will be able to see the areas you are unable to see clearly on your own.

Anything that does not look normal and healthy will be carefully evaluated with dental equipment and technology; X-rays of your entire mouth or a concerning section may be taken for a closer look which will determine what you need. The treatment that you will end up going through with will be dependant on your diagnosis.

Filling options

Composite rescue

These are made up of a mixture of plastic and fibreglass particles. They have been used for both larger and smaller fillings especially in the front more visible teeth because they can match the colour of your teeth.


Most commonly made from ceramic materials, which are used for a variety of treatments besides fillings - such as veneers, implants and dental crowns. Ceramics are often favoured because they are resistant to staining and abrasions.

Cast gold

These are visible because they are gold in colour. They are made up of gold alloy, a mixture of gold and other metals. This material is the same one used on inlays and overlays. The advantage is that the material does not corrode.

Glass ionomer

This material consists of acrylic and fluoro-aluminosilicate, a type of glass component. The cost is usually comparable to composite resin.

We are advocates of white fillings like ceramics and composite resins material fillings. They are known to be stronger and more durable than silver amalgam fillings. Additionally, they can be perfectly matched to your tooth's natural colour. Whether you need a new filling or would like to replace an old silver filling with the new tooth-coloured variety, we can help you.
