Pregnancy Risks, Perinatal Death and its link to Dental Amalgam Fillings

CHAMPIONSGATE, Fla., Dec. 19, 2018 /PRNewswire/ — Two new studies associating dental amalgam fillings with pregnancy risks confirm action is urgently needed to protect babies from the known risks of mercury, according to the International Academy of Oral Medicine and Toxicology (IAOMT). A growing number of countries have taken measures to prevent the placement of dental amalgam “silver” fillings in women and children because it contains approximately 50% mercury. However, dental amalgam is still used widely in the United States with no restrictions for these or other susceptible populations.

One of the new studies by researchers in Norway involved over 72,000 pregnant women with data on the number of teeth containing dental amalgam fillings. Lars Bjorkman and his co-authors discovered a “statistically significant association between the number of teeth filled with dental amalgam and the risk of perinatal death.” Their research was published earlier this month in the peer-reviewed journal PLOS One.

Another new study by researchers in Egypt investigated the pregnancy outcomes, urinary mercury levels, and blood antioxidant activities of a cohort of 64 pregnant dental staff and 60 other pregnant women. They found that pregnant dental staff “suffered higher odds of developing spontaneous abortion and pre-eclampsia and giving birth to babies smaller for gestational age.” The study appeared earlier this year in the peer-reviewed medical publication The International Journal of Occupational and Environmental Medicine.

“The use of dental mercury must be stopped,” says dentist Michael Rehme, DDS, IAOMT President. “No one should have toxic mercury put into their mouth where it continuously leaks, especially when brushing or chewing. These studies validate decades of research demonstrating this outdated dental material poses a substantial threat to human health.”

This summer, the European Parliament enacted a ban on dental amalgam fillings for children under 15 and pregnant and breastfeeding women with consideration for banning dental amalgam completely by 2030. Other world regions have likewise taken action against dental amalgam, largely due to a United Nations Environment Programme (UNEP) treaty created to protect human health and the environment from the adverse effects of mercury.

Meanwhile, in spite of burgeoning scientific research and global action, the U.S. Food and Drug Administration (FDA) “considers dental amalgam fillings safe for adults and children ages 6 and above.” However, details in the FDA’s public statements about dental amalgam have varied over the years, including information about its potentially harmful impact on women during pregnancy (and their fetuses) and children under the age of six. Unfortunately, there are no enforced FDA regulations for children or any other population.
