Before eating fish, every pregnant woman should ask, "How does mercury affect a pregnancy?" While, for the most part, fish is quite nutritious, it can also contain some very unhealthy contaminants. Mercury is one of them. The mercury found in fish can affect a fetus' nervous system as well as its brain development. The Food and Drug Administration has released specific guidelines for women, both who are pregnant and those who are trying to become pregnant. They state that a pregnant woman should eat no more than 10-12 ounces of low mercury fish per week. Fish that are ranked highest in mercury content should be avoided altogether, and those with "high" rankings should not eat more than three times per month at 6 ounces per serving.

During a woman's pregnancy, she can pass mercury to her unborn child through the placenta. Mercury can also affect breast milk and, according to biological dentists, can be transferred to various parts of the body via dental fillings that contain mercury and, again, transferred to the unborn child. The health problems that can arise for the developing fetus can be severe. Not only are their brains and nervous systems affected, but mercury can also place them at greater risk for heart and cardiovascular system problems. How does mercury affect a pregnancy? The effects can be devastating.

The dentist stated that the polishing causes mercury vapor to be released into the pregnant woman's body and to may be passed on to the fetus through the placenta.

Dentists have used silver amalgam to fill cavities for over 160 years. Silver amalgam contains about 50% mercury. German physicist, Dr. Josef Issels, was one of the first dentists to note that the toxins from mercury in fills could harm a person's overall health. The warnings should be emphasized even more for women who are pregnant. How does mercury affect a pregnancy?
