Fillings are a way to restore a tooth when there is structural loss, typically a result from dental caries or trauma. It is used to restore its natural looks, integrity and function. If you have a cavity, your dentist may keep an eye on it (if it’s small) or want to fill the cavity as soon as possible. If a large cavity is not filled, it can get bigger, cause pain and become infected. The tooth may require bigger treatments such as a root canal and in some cases, even have to be removed and replaced with an artificial tooth.

White composite resin filling


Also known as white fillings, they are a more esthetic option to silver fillings (amalgams). The white filling can be matched to be the same color as your natural tooth. They come in different shades of tooth color such that if applied with proper skill they can achieve highly esthetic smiles as in « direct composite veneer » application or to close gaps between teeth. To place this filling, your dentist cleans all decay from the tooth and puts a bonding material on the inside of the cavity. Composite resin is put into the cavity in thin layers. Each layer gets hard with the help of a special blue 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 just like a natural tooth. A white composite filling can be used for any one of the following reasons:

  • Dental cavities
  • Close gaps between teeth (diastemas)
  • Direct composite veneers
  • Cement crowns, inlays, or onlays
