When treating a cavity, the dentist will remove the decayed portion of your tooth and fill it with another substance. This procedure is called a filling. There are multiple options for the material to be used in the filling, the most common of which are composite fillings and amalgam fillings (silver-coloured filling material).
A composite filling is also known as a tooth-coloured filling, since the material used in the filling can be closely matched to the colour of your teeth. Composite fillings provide good durability for small to medium cavities, and the procedure typically involves removing less of a tooth than you would during an amalgam filling. They are well suited for treating front or highly visible teeth because of their natural look.
When can a composite filling be used?
- Decayed tooth (i.e. cavity)
- Chipped or broken teeth
- Decreasing the gap between teeth
How its done
- The dentist numbs the area where the filling is to be placed.
- He/she will remove any decayed portion of the tooth.
- A bonding agent is applied, and hardened and cured with a special light.
- The filling is applied in thin layers to slowly form the complete filling.
- The dentist will smooth and polish the filling to be comfortable and fit your bite.
