Composite fillings are also called plastic or white fillings. To place this filling, your dentist cleans all decay from the tooth and puts a glue (or bonding material) on the inside of the hole. Composite resin is put into the hole in thin layers. Each layer gets hard with the help of a special light that your dentist holds over the tooth. When the last layer of the filling is hard, your dentist shapes the filling so it looks and feels natural.
There are several shades available in these type of material that makes them number one choice for repairing teeth in the aesthetic zone. New materials are now BISGMA free.
Advantages of white fillings
- These fillings will be the same colour as your natural teeth.
- They cost less than gold fillings.
- They are direct fillings, so they can be done in one appointment, in most cases.
- Composites are bonded in the cavity. This allows your dentist to make more conservative repair to your tooth, meaning, less tooth structure is removed during the procedure.
