Is Dental Amalgam Safe?
If you have one of these fillings, there's no need to worry. The FDA has determined that the low levels of mercury vapor emitted by dental amalgam fillings are safe for adults and children ages six and older.
While the developing neurological systems in fetuses and young children may be more sensitive to the effects of mercury vapor, the FDA found little to no clinical data regarding any long-term health effects of mercury on pregnant women, developing babies, or children under the age of six. Further, the amount of mercury found in mothers’ breast milk with amalgam fillings is very low. There is no evidence suggesting an association with breastfeeding mothers with amalgam fillings and dangerous mercury levels in breast milk.
Although amalgam fillings are safe for the vast majority of patients, some individuals may have an allergy or sensitivity to either mercury or one of the other metal components of dental amalgam. This may cause these individuals to develop lesions in their mouths, allergic reactions, or other side effects. In these cases, the FDA notes that dental professionals should use alternative materials.
