Tooth Coloured Filling

are strong, but may not be as hard wearing as ordinary amalgam fillings. Composite fillings are tooth coloured and are made from powdered glass, quartz, silica or other ceramic particles added to a resin base. The dentist will choose a shade to match your own teeth, although over time the filling can get stained. After the tooth is prepared, the filling is bonded onto the area with an adhesive and a light shone onto it to set it. With this type of filling, the dentist may have to remove less of the tooth, which is obviously better.

Glass ionomer Glass ionomer fillings form a chemical bond with the tooth. They may also release fluoride, which helps prevent further tooth decay. This type of filling is fairly weak. Because of this, they are usually used on baby teeth and non-biting surfaces, such as around the neck of the tooth. Little preparation is needed as the filling bonds directly to the tooth.

Porcelain inlays Your dentist can now use computer technology (called CADCAM) to design and prepare perfectly fitted porcelain inlays in just one or two visits. Porcelain inlays can also be made in a laboratory, but this will need at least two visits to your dentist. Porcelain can be hard wearing and long lasting, and it can be coloured to match your own teeth. This type of filling can be quite expensive.
