White Composite Fillings
Until recently, you had no choice about the color of your fillings. Now you can have old silver or gold fillings replaced with nearly invisible porcelain or resin restorations.
A composite resin is a tooth-colored plastic mixture filled with glass (silicon dioxide). Introduced in the 1960s, dental composites were confined to the front teeth because they were not strong enough to withstand the pressure and wear generated by the back teeth. Since then, composites have been significantly improved and can be successfully placed in the back teeth as well. Composites are not only used to restore decayed areas, but are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
How is a composite placed?
Following preparation, Dr. Robertson places the composite in layers, using a light specialized to harden each layer. When the process is finished, he will shape the composite to fit the tooth. He then polishes the composite to prevent staining and early wear.
How long does it take to place a composite?
It takes Dr. Robertson about 10-20 minutes longer to place a composite than a silver filling. Placement time depends on the size and location of the cavity – the larger the size, the longer it will take. |
