A filling replaces a part of the tooth that has been lost because of accidental damage or decay.
Silver fillings are made of amalgam – a mixture of mercury with other metals. They are very strong, but obviously don’t match the colour of your teeth.
The alternative is what are called ‘white fillings’, which come in a range of shades, so they can be matched to the colour of your own teeth. .
Sometimes white fillings can be used to cover unsightly marks on teeth.
The technology behind white fillings has improved considerably in the last few years, and their strength will now match that of amalgam fillings.
