Filling a tooth literally means that the dentist places material into or onto a tooth to repair it.
Fillings are usually needed because decay has caused a cavity to form or because a tooth has been broken or chipped.
There are two basic types of dental filling available: amalgam and composite.
Amalgam fillings are made of mercury, silver, copper and tin.
Composite (also known as "white" or "tooth coloured") fillings are typically made of glass particles, resin and a setting ingredient.
Many patients prefer tooth coloured fillings because they look natural and other people can't see them when you laugh or smile.
Composite fillings are often called "white fillings" but we actually use a wide range of different shades to exactly match the natural colour of your teeth.
