Out with the old Amalgam
Restoring the function and appearance of your smile with tooth-coloured fillings
Composite Resin is the material of choice for restoring teeth to their former strength and beauty. Gone is the need to use unsightly metal amalgams, which contain mercury. In contrast to amalgam, composite resin is tooth-coloured and provides a more attractive and appealing smile.
We use composite resin or porcelain inlays/onlays which are bonded to the tooth structure to restore teeth or to replace old amalgam fillings, ensuring the aesthetics and function of your smile. Many people enjoy better health after having their old amalgams replaced.
Dental Amalgam is a mixture of mercury, silver, tin and other trace elements including copper. Mercury, which makes up about 50 percent of the compound, is utilised to bind the metals together to provide a strong, hard, durable filling. After years of research, mercury continues to be the only element that will bind silver and tin together in such a way that it can be easily manipulated to fill a cavity. However, thanks to advances in dental technologies, you can now receive the restorative and protective dental treatment you need without having to compensate the aesthetics of your smile, or have mercury products in your mouth.
In contrast, porcelain and composite resin restorations do not contain toxic mercury and since they don’t contain metal, they wont expand and contract at a different rate than your natural teeth causing cracking and possible root fracture.
Composite Resin restorations are made of ceramic and plastic compounds that compliment the appearance of natural tooth colour. For this reason composite resin may be used not only on back teeth but also in the front teeth. In its early stages, approximately 20 years ago, composite resins were placed mainly in front teeth because they weren’t reliably strong enough to withstand high-pressure grinding and chewing performed by back molars. However, thanks to advancements in dental technology, resin compounds can now be used to support your back teeth, providing a strong, durable and protective layer over the teeth. A tooth well restored in composite resin is nearly as strong as natural tooth and certainly very much stronger than a tooth filled with amalgam. The latest and best airplanes are now built with composite resin – not amalgam!
The procedure for placing a composite resin dental restoration is more complex that the application of an amalgam filling. The procedure includes:
Some patients may choose a longer term material such as porcelain for their restorations.
For reasons such as:
