White Fillings

The dental filling is the bread and butter of modern dentistry. 

Why would I need a White Filling?

There are many reasons teeth can benefit from white fillings. These include:

  • fixing a decay (hole) in a front or back tooth

  • improving the colour of a front or back tooth

  • improving the shape of a front or back tooth AKA 'resin veneer' / 'bonding'

  • improving the biting surfaces of front or back teeth

  • protecting exposed root surfaces of teeth that have been damaged due to acids

  • replacing an old silver filling (amalgam) that has created cracks in your tooth

  • replacing an old silver filling (amalgam) or white fillings that have broken or gotten decay underneath it

What are White Fillings made of?

White fillings, known as composite resin or composite resin fillings, are synthetic materials that combine tiny filler particles of glass, mineral, or resin in a mouldable matrix. There are coupling agents that join the fibres together when blue light is applied. This means the resin material can go in to the cavity surface and adapt into all the nooks and crannies. Once the blue light is applied, the resin sets hard and is safe to chew on. 

The type of filler particles, the percentage of filler in the matrix, and the size of the filler all determine the physical properties of the resin, and which resin is best applied in different parts of the mouth.

What is super important is the attachment of the dental filling to the tooth, this is known as the 'bond'. Having a strong bond means less likelihood of sensitivity, less chance the filling will get decay under it again, and a. stronger filling. At Dentista we strive to follow 'Biomimetic' protocols. This means we use the gold standard materials and techniques and take the time and care necessary to create a strong bond of the dental filling to your tooth. Not all dental fillings are created equal!

Cerec Ceramic Fillings

Up until the advent of cerec dentistry, a large filling needed on a tooth would have to result in a patient receiving a full crown. A large filling, that could not be treated by filling the tooth with a plastic substance, due to it being so large, meant that a crown had to be cut. This is turn meant that a lot of the patients tooth had to unnecessarily be filed down in order for the crown to be placed effectively. One of the main reasons Dentista have invested in the CEREC is to provide our patients with a better treatment option to a full crown

The name given to ceramic fillings is onlays or inlays. They fall under the 'major dental' category of health insurance.

White fillings are excellent and for the most part are the backbone of modern dentistry, but they are not always the most effective tool when we are talking about a very large filling. We are, after all, with white dental fillings, talking about filling a tooth with plastic, and so with this they have their limitations.


 If you have a very LARGE WHITE FILLING, (bigger than half your tooth) then then your dental filling will experience a large amount of bending. There can be problems with staining, breaking of the filling, and NEW DECAY getting in under the white filling (where it bends at the seam where it meets the tooth). Remember that anywhere, where there are bends or joints, that aren't bonded extremely well, leave the door open to decay.


As mentioned earlier, a full crown requires all surfaces of the tooth to be shaved down, and thus also means that alot of healthy tooth is removed, somewhat unnecessarily.

The cerec provides us with an opportunity to do CERAMIC FILLINGS. This means you have a restoration that is much stronger than the white plastic fillings, uses superior and stronger materials, lasts much longer, and doesn't remove any healthy structure unnecessarily like a crown would.

So why is it that ceramic fillings are not usually offered with traditional (2 appointment from the laboratory) ceramics? Well they were and still are, however all you need to do is ask any one who's had them and they're a bugger to have the temporary - which often falls off! This means dentists are reluctant to offer them because the temporaries are a headache for the patient and for the dentist!

The cerec eliminates the need for a temporary, which in turn means less visits to the clinic and less change for things to go wrong. The cost of a ceramic filling is more then a white filling, you are getting a better quality restoration. Depending on your private health insurance this may be a few hundred dollars.
