Fillings Back

Composite fillings are also called plastic or white fillings. This kind of filling will depend on where the tooth is in your mouth. We bite down harder on our back teeth when we are eating, so plastic fillings might not be the best choice. Be sure to talk to your dentist about all the options available to you.

Placing a filling is done by cleaning all the decay from the tooth and glue is placed (or bonding material) on the inside of the hole. Composite resin is then put into the hole in thin layers. Each layer will get harder with the help of a special light that the doctor will hold over the teeth. When the last layer of the filling is hardened, the dentist will shape filling so it looks and feels natural.


  • 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.
  • This kind of filling can break more easily than amalgam or gold fillings, and may not last as long.
  • Composite fillings cost more than amalgam fillings.
  • Recurrent decay is more of a problem than with amalgam or gold fillings.
