These are restorations which replace lost tooth structure. They are suitable when the lost tooth structure has not progressed into the pulp or too far down the root of the tooth.
Our filling materials are the highest quality on the market and are made in the USA, Switzerland or Japan. Our porcelain fillings are sourced from labs in Northbridge and Edgecliff. You should expect nothing but quality - after all, it's going to stay in your mouth for years!
Composite Resin “White Fillings”
Composite Resin is a plastic-type material with small tooth-coloured glass particles. It is bonded to the tooth and sets hard in the presence of blue light.
- Suitable For? Most restorations, both large and small. Especially suitable where aesthetics are important. The multi-step bond with the tooth is one of the advantages of Composite Resin over amalgam fillings. It can even be layered as veneers in some cases
Amalgams are metal fillings made up of a combination of silver, tin, copper and mercury. The silver, tin and copper are in powder form, and when mixed with the liquid mercury, forms a soft material which sets hard.
- Suitable for? Large fillings in back teeth that need to resist heavy chewing and grinding forces. As amalgam does not “bond” to the tooth, extra drilling must be used to create retentive features to retain the amalgam.
Glass Ionomer & RM Cement
This material is a combination of glass particles which reacts with a silicate acid to harden. Some have resin added to improve strength properties. It chemically bonds to the tooth.
- Suitable for? Fillings that are either temporary (root canal temporary fillings, fillings in baby teeth), permanent fillings in areas of minimal load (away from the biting surface such as on the root of the tooth) or fillings that cannot be kept dry. It has a chemical bond with the tooth.
Porcelain Inlays and Onlays
These restorations are “made and set” in a lab. They are usually porcelain, ceramic or resin.
Inlays: Named, because it’s bonded in, or “lays in” a prepared cavity in a moderately damaged tooth.
Onlays: So named, because it is bonded onto, or “lays on top of” part of a prepared cavity in a more significantly damaged tooth.
Suitable for? Fillings where there is a particularly heavy bite and where both strength and aesthetics are required. Usually two visits are required.
Are amalgam fillings bad for you?
Most people are concerned about the mercury content in amalgam. For a person with 10 amalgam fillings, the daily amount of mercury released is 1.7μg. This is similar to trace amounts found in fruit, vegetables and eggs. By comparison a can of tuna can contain 20μg of mercury. Links to patients with health conditions including cardiovascular diseases, diabetes, cancer, Alzheimer's disease, multiple sclerosis and Parkinson's disease have not been proven despite numerous studies and have been rejected by the WHO (World Health Organisation) and FDI (Word Dental Federation). The only proven side effect in some people is a localised allergic reaction.
Should I replace my amalgam fillings?
Unless the amalgam shows signs of chipping, cracking, leakage or adjacent decay, replacing an amalgam in a non-aesthetic area may be unnecessary. The tooth may be further weakened and/or risk becoming uncomfortable. Replacement should always be discussed with your dentist first.
