FILLING MATERIALS

AMALGAM COMPOSITE GOLD

1 Made of a metal mixture containing mercury, silver and others, these have been used by dentists for well over 100 years. They are durable fillings that can protect a tooth over multiple decades.

2 Although not as hardy as amalgam or gold, composite fillings are made from a combination of ceramic particles and are tooth-coloured, allowing a filling to appear more organic.

3 Unlike composites and amalgam, gold fillings are made in laboratories following dental impressions. Although more expensive and labour-intensive, gold fillings are strong and do not tarnish, allowing them to last for many years.
