Amalgams are metal filings consisting of approximately 50% mercury. The mercury reacts and binds with silver, copper, tin and alloy particles to form amalgam. Composites or tooth colored fillings have improved drastically over the past few years, and dentistry has been steering away from amalgams. Amalgam’s toxicity has been a very controversial topic for quite some time. We do not recommend removing non-decayed amalgam. However, as with any type of filling material, amalgams may develop secondary decay or recurrent cavities. When this occurs, we recommend removing both the amalgam and decay and restoring your tooth to a healthy state with a non-metal restoration.
