Approximately 50% of a dental amalgam filling is made up of liquid mercury, while the other 50% is a mix of a powdered alloy of silver, tin and copper. Mercury is used because it binds the alloy particles together to make the filling strong.

Although we know that high levels of mercury vapour exposure can cause adverse effects in the brain and kidneys, the FDA says that amalgam fillings are safe for use in children over the age of six and adults. Clinical studies have not been able to prove a connection between amalgam fillings and health problems in the general population, and many people argue that the quantities of mercury in amalgam fillings are just too small to be dangerous.

On the flipside, there is a great deal of anecdotal evidence to suggest that some people do have a sensitivity to mercury with symptoms that only improve once their amalgam fillings are removed. However, many of the symptoms associated with mercury exposure are common symptoms of other conditions.

We would always advise you to do your own research and to discuss any concerns you have with us. If you would prefer to not to have any amalgam fillings or you would like us to replace a damaged filling with a white composite material, our safe amalgam removal means you can have peace of mind about mercury exposure.
