Amalgam Fillings
Dental amalgam is the traditional silver-coloured filling we are all familiar with. Research into the safety of dental amalgam has been carried out for over a century and to date, no trustworthy controlled studies have found a connection between amalgam fillings and any medical problem.
Whilst composite (tooth coloured) fillings are becoming more popular, amalgam fillings represent the most durable and long-lasting form of filling available. (Apart from gold fillings which are more expensive.)
