White fillings
Modern dentistry has progressed rapidly in the field of aesthetic tooth coloured mercury-free fillings. White fillings were introduced in the 1960s and through technological advances, we now have the so called 5th generation bonding systems to enable teeth to be successfully restored with strong, durable and smile enhancing fillings. Unlike silver (amalgam) fillings, white fillings stick to teeth, so they can be used to repair teeth that have been chipped, broken or decayed. White fillings can also be used for cosmetic improvements by changing the colour of the teeth or reshaping disfigured teeth.
Aesthetics are a distinct advantage with these fillings, as we can blend shades to create a colour nearly identical to that of the actual tooth. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes. Studies have shown that most composite fillings last for 7-10 years.
Some of the newest white filling materials leach out fluoride which helps to prevent further decay in the area.
Different types of white filling are available and are indicated for different purposes and sites in the mouth. These include composite fillings, glass ionomer fillings or a mixture of these two types, the compomer fillings.
