I have old silver fillings from a long time ago that I want to have removed and replaced with white ones instead. One dentist told me it was safer to keep the silver ones, as more mercury can be released during the removal process. Is this true? — Marcia
Marcia,
There are some who are concerned that silver fillings due in fact release mercury gas, with the potential to cause health hazards over time. Since mercury is a toxic substance that can cause many health issues, it’s important that old amalgam fillings (which can contain more than 50% mercury) be removed in a safe manner.
Mercury from your old fillings can be released into your body several different ways (i.e. chewing, brushing or teeth grinding). However, the most dangerous way it can be released is through removal; especially if it’s not done in a specific manner. Traditional dentists remove amalgams regularly with little regard to mercury vapor exposure.
Seeking out a specific “mercury-free dentist” places you in the care of someone specifically trained to safely remove old amalgams, minimizing the effect of mercury exposure. They will likely have all the necessary equipment and tools to do the job safely. Currently, the ADA recognizes mercury containing amalgams as acceptable filling material. With that being said, many dentists will use it regularly, as well as advise not to remove them unless there is decay or cracks. As a patient, it’s important to do your own research about the hazards of mercury-based fillings, and look to a mercury-free dentist that can replace them.
