Will have to update this post soon.

According to Dentalblogs , the Philadelphia City Council is set to vote on the Mercury in Dentistry Bill which (if it passes) will require dentists to inform patients about the mercury content (50%) of amalgam fillings and that it could be hazardous to their health.

Some research indicates that amalgams with mercury (in excess, probably) can cause hair discoloration, hair loss, gum disease, migraines, memory loss, anxiety, mental lethargy, chronic fatigue, eczema, asthma, kidney disease, backaches, arthritis, and hormone problems. Not to mention Alzheimer�s disease, Parkinson�s disease, MS, ad other neurological disorders, DNA damage, and many others.

So why still use amalgam? It�s less expensive compared to aesthetic restorations. The ADA has already deemed amalgams as safe. But to be on the safe side, many dentists have voluntarily chosen to place only composite resin fillings because of their aesthetic appearance and safety issues.

Governments in Maine, New Hampshire, and California are also considering similar laws.
