A filling is a structural replacement for a part of a tooth that has been lost through accidental damage, decay or wear.
There are several types of white filling these include “Composite”, “Glass Ionomer” and “Compomer”.
- The tooth is “numbed” if necessary – if a filling is small then it may not need an anaesthetic.
- The tooth is prepared to accept the filling, this involves removing any decay / old filling material and ensuring that the remaining tooth structure is sound.
- The tooth is washed and dried using water and air.
- The tooth surface is then etched with a mild acid to allow the filling to adhere to the tooth.
- A bonding agent is then is then applied to the tooth which is “set” using a blue light (a shield is used to protect the eyes). This is called “Light-curing” or “Light-set”
- The filling material is then placed in the prepared cavity and shaped; this is then Light cured”.
- Finally the new filling is polished and trimmed as required.
