A. Metal fillings are made of silver/amalgam, and they are designed to last
about eight years. An old amalgam filling may break down, leak, or decay can begin under the
filling. Furthermore, the FDA recently overturned its stance on amalgams. You see, dental
amalgam contains mercury, a harmful heavy metal. The FDA now warns people who are pregnant or
have mercury allergies, as well as young children, to avoid amalgam fillings. At Zenith
Dentistry, we place tooth-colored fillings, crowns, inlays, and onlays, so you can have peace of
mind that your dental work does not contain harmful mercury. White dental work will also keep
your smile white and beautiful, so you can eat and speak with confidence.
