One of the most hotly debated issues among dentists these days is whether or not old, silver amalgam fillings in the mouths of so many Americans are safe.
“A lot of patients are not even informed that silver-colored fillings are actually 52 percent mercury,” said Curatola. “There's also research – and it's proven that mercury leeches out over time from these silver fillings – more if you drink hot liquids and chew things. My opinion is that I don’t think any amount of mercury is good, and especially if [these fillings are] breaking down, they should be replaced.”
Mercury is a powerful neurotoxin that at certain levels has been linked to autoimmune diseases, neurological issues, chronic diseases and even mental disorders. One concern among dental professionals is that people with amalgam fillings who grind their teeth, chew gum and drink hot or carbonated drinks could be exposed to a dangerous level of mercury vapors.
