First, the fillings are made of approximately 50% mercury, which we know is a hazardous material.
Second, the metal fillings expand and contract at a different rate than the tooth, resulting in cracks opening between the tooth and the filling. These openings let bacteria get in and start decaying.
Third, the silver amalgam fillings expand over time, like ice cubes in a tray. As a result, dentists often see teeth break with no apparent cause.
And fourth, these fillings are ugly and unnatural looking. If you have unattractive silver amalgam fillings, you can replace them with natural looking laser-bonded fillings and onlays.
In addition, we find that many of these old fillings have a lot of decay under them.
Now that dentists understand the problems associated with silver mercury amalgam fillings, and there are excellent alternatives, there is no reason why anyone should have those old-fashioned, ugly fillings in their teeth anymore.
