What Are White Fillings Made Of ?

When you're deciding on restoring or repairing your teeth, make sure it's an informed decision about which filling is best for you. Here's why we only choose composite or white fillings for our clients.

Fillings (from whatever material they are made from) help to restore the function and shape to your dmaged or decayed teeth. Composite ( AKA white or natural  coloured ) filings are typically made from an acrylic resin combined with a powdered glass mixture, taht is bonded to your tooth and then hardened with a high-intensity blue light. Here at Hobsonville Point Dental we choose to always use white fillings as we belive there are many advantages over an amalgam or metal/silver filling.electron scanning microscope image of composite resin

Because of the materials that composite or white fillings are made from, these natural coloured alternatives to silver (amalgam) fillings can be easily shaded to match your existing teeth, making the resulting proceedure far less visible. Our clients prefer a natural looking smile without unsightly black or silver teeth, so composite fillings are the preferred choice for cosmetic improvements for changing the colour or reshaping damaged or misshapen teeth. 

Do White Fillings Contain Mercury?

Traditional amalgam (or silver or grey metal fillings) typically contain 50% mercury as well as with tin, copper, silver or zinc, while white (composite) fillings do not. 

As you already are aware, many local dental practices continue to use amalgam fillings (considered by some as controversial) but at Hobsonville Point Dental we have been mercury free for all of our restoration work since opening.  

Of great importance to us is ensuring the preservation of your natural tooth and durability of proceedures, so our team consider there to be no advantage (but instead a distinct disdavatntage) in the use of silver amalgam versus composite resins (or white fillings).

Here Are The Other Options For Fillings - Gold and Porcelain Crowns.

As one of the most durable and long-lasting options for dental restorations, gold is an effective choice for fillings - however it is one of the most expensive options which also needs to be mechanically retained, i.e., they need to be keyed into a cavity which can destroy the tooth structure unnecessarily.

Porcelain fillings are another indirect option, that although are higher in cost -  do provide a very natural appearance, helps prevent the further spread of decay, protects the strength and function of teeth and can also be used to correct an uneven tooth surface.

So although there are fillings or restorations that are made from a range of materials, we suggest contacting Hobsonville Point Dental today on (09) 320 0504, and we can help you identify the dental solution best suited to your needs.
