How do I know if I have amalgam fillings?

Amalgam is a silver metal that was once a popular filling material because of its hard-wearing qualities. While they start out silver, amalgam fillings gradually lose their shine and eventually turn dark grey. In recent years, most dentists have switched to using composite fillings which are the same colour as tooth enamel. If your fillings were done in the 80s or 90s and are a silver-grey colour, then they will be made of amalgam.

Why do I need to replace my amalgam fillings?

Amalgam fillings contain about 50% mercury. Studies have shown that when you chew or grind your teeth, small amounts of mercury vapour are released from the amalgam and absorbed into your bloodstream. Although this amount is considered to be within safe limits, some people may be sensitive to the effects, or have an allergy to mercury. From an aesthetic perspective, amalgam fillings can be unsightly, especially if they are near the front of your mouth and easily visible when you smile or talk. From a mechanical perspective, over a long period of time large amalgam fillings cause fracture propagation in your natural teeth and this can lead to a broken tooth, or worse, needing to have the tooth extracted.
