Tooth decay results in tooth cavities and can recur even in filled teeth. Silver amalgam fillings are still carried out routinely but many patients opt for white fillings.

White fillings are known as composites and are more natural in appearance. On a chemical level they bond to the remaining tooth.

Onlays and inlays are custom laboratory made fillings which are cemented onto the tooth. These can be a good alternative to a full crown and where a normal filling cannot be placed. A choice of materials is available, ranging from composite to porcelain to gold.
