A filling replaces the part of a tooth that has been lost because of decay, accidental damage, or long term wear and tear. We offer two types of filling:

White - these stick to teeth, so they can be used to repair those that have been chipped, broken or have decayed. White fillings can also be used for cosmetic improvements by changing the colour of the teeth or reshaping disfigured teeth.

Different types of white filling are available and are indicated for different purposes and sites in the mouth. These include composite fillings, which bond to the tooth to support the remaining tooth structure, and glass ionomer fillings.

Metal (amalgam) - these can last for a long time but can also darken teeth. In teeth with large amalgam fillings, there is an increased risk of tooth fracture. Amalgam fillings do not add to the strength of a tooth so the tooth is still only as strong as the remaining tooth structure. In these heavily filled teeth, then, the unprotected parts are prone to breaking away. It is often necessary to further protect these teeth with crowns.


We will advise that a crown is necessary if a filling is not sufficient enough to protect, support and restore the appearance of a tooth.

A porcelain crown is placed on a weak or cracked tooth above the gum line to hold it together and prevent further damage. Crowns can also be used to support the remaining tooth structure when a large filling has been used and there is a high risk of the tooth fracturing away.
