Composite resins are tooth-coloured fillings made of a plastic mixture filled with glass or silicon dioxide. They’re used in place of traditional silver fillings for a more natural look.
When applying a composite resin filling, your dentist will prepare the decayed tooth as he normally would. Then he’ll insert the composite and use a special light to harden the material. Lastly, he’ll shape the composite to properly fit the tooth and polish it to prevent staining and early wear.
You may experience tooth sensitivity for a short time after having the composite placed. If you drink a lot of coffee or tea, the colour of the composite can change slightly. If you wish, your dentist can put a clear plastic coating over the composite to prevent the colour from changing. Composite fillings last seven to ten years.
