Composite fillings and glass ionomer fillings
Although amalgam has a successful history, it has always detracted from white teeth and a beautiful smile. Composite fillings consist of acrylic resin and finely ground glass-like particles mixed to a paste consistency to produce a tooth-coloured restoration, so you can retain your natural looking smile.
Composite fillings have excellent durability and resistance to fractures in small-to-mid size restorations that need to withstand moderate biting and chewing pressure.
One of the benefits of placing composite fillings is less natural tooth surface is removed when preparing your tooth. This results in a smaller filling than if an amalgam filling were placed.
Glass ionomers are tooth-coloured materials made from a mixture of acrylic and fine glass powders that are utilised to fill small cavities, particularly those on the root surface of teeth. Glass ionomers are able to release a minute amount of fluoride that may be beneficial for patients who are at high risk of decay. When the dentist prepares the tooth for a glass ionomer, less tooth structure is removed. This may result in a smaller filling than if an amalgam filling had been used.
