About White Fillings
As well as filling dental cavities and root canals, white fillings are also frequently used to restore broken, chipped or worn down teeth. Compared to traditional ‘black’ amalgam fillings, they offer patients a number of substantial benefits:
Colour matched – Formulated to resemble the natural colour and lustre of existing teeth, making the camouflaged filling undetectable to onlookers.
Metal-free – Made from a 100 per cent metal-free mixture, white fillings contain no potentially harmful mercury and can be shaped to replicate a natural tooth.
More support – Less tooth structure is removed when preparing the filling and it is chemically bonded to the tooth, providing increased support.
Reduced sensitivity – Metal is a thermal conductor and patients with black fillings can have a sensitive reaction to hot and cold foods or beverages. Sensitivity is not usually a problem with white fillings.
White fillings, or composite resin fillings, are a great way for people to hide the fact that they ever had a cavity in the first place. Made from a combination of glass and plastic tooth-coloured materials, they are designed for aesthetic dental restorations while also serving to restore natural tooth function and maintain oral hygiene.
