Until recent times, the majority of fillings were done using dental amalgam, which is sometimes known as a silver filling. However, technology has improved and tooth-coloured fillings that are just as strong while also providing the look of natural teeth, are now the material of choice for most dentists.

What Are White Fillings?
White tooth filling can refer to several types of tooth-coloured fillings made from different materials:
Ceramic fillings are made from a porcelain material that is generally stronger than other types of filling materials, including amalgam. These types of restorations are generally more expensive than the other types because they require additional preparation by a technician in a laboratory. They are made to mimic the look and feel of the natural teeth, which makes it difficult to tell the difference between the filling and the natural tooth surface.
Composite resin fillings are made from an acrylic resin. The resin can be closely matched with the colour of your teeth for a natural look. Composite resin fillings may be used in restoring broken, chipped or worn down teeth.
Glass ionomer fillings include acrylic resin combined with fluoroaluminosilicate, which is a material found in glass. This material releases fluoride over time to help give added protection to the teeth. These white fillings are not as strong as composite resin and are typically only used for fillings that fall below the gum line. They may also be used in children.
Why are White Fillings Important?
Fillings are important as they help to seal a damaged tooth or tooth cavity and prevent additional damage to a tooth. In addition, you can also expect to get natural-looking results with white fillings. If you are not sure if you need fillings, talk to us about your options.
