The use of amalgam in pregnant women is controversial because it is understood that mercury is released from amalgam fillings and it is known that mercury causes congenital anomalies.
Recent studies confirm that the amount of mercury vapor released from amalgam is well below the toxic level. It has been understood that this amount will not cause harmful effects.
However, while there is no evidence of a link between amalgam use and birth defects or death, it is recommended that dentists carefully use or remove amalgams from the mouth.
