NEW RESEARCH CONFIRMS MERCURY EXPOSURE OF MAJORITY OF AMERICANS FROM MERCURY DENTAL FILLING FILLINGS EXCEEDS CALIFORNIA SAFETY LIMIT
In the A current studyresearchers David and Mark Geier examined the urinary mercury excretion of more than 150 million Americans using the CDC’s National Health and Nutrition Examination Survey (NHANES) 2015-2018 survey. The Geiers found a highly significant relationship between the number of dental amalgam filling surfaces in the mouth and the amounts of mercury excreted. They compared the amounts of mercury excreted to the current minimum risk levels of mercury from the US EPA and California EPA.
It is important to note that the number of surfaces is not the same as the number of fills. Each tooth has five surfaces, which means a person with a single filling can have up to five surfaces.
Of the 91 million (57.8%) adults who had 1 or more mercury filling surfaces, the amount of mercury in their urine was significantly correlated with the number of amalgam surfaces. The Geiers wrote that, “Daily doses of Hg vapor from amalgam fillings exceeded the most protective doses California Environmental Protection Agency (EPA) safety limit for approximately 86 million (54.3%) adults”. The US EPA Minimum Risk Level (MRL) for mercury is significantly higher than the CalEPA MRL due to the fact that by law the CalEPA MRL must protect vulnerable people, and not the average. However, 16 million adults are exposed to mercury levels above the US EPA MRL.
Similar information about excessive exposure was presented by the IAOMT at the 2010 FDA expert hearing on the safety of amalgam and a dentist on the panel asked the Agency’s experts for the Toxic Substances and Disease Registry (ATSDR) how much you can exceed the MRL go and still be safe. dr. Richard Kennedy of the ATSDR explained that one cannot exceed the MRL and expect to be safe.
In September 2020the Food and Drug Administration (FDA) updated risks of dental amalgam for sensitive groups and identified fetal exposure during pregnancy as the most critical exposure and recommends no amalgam fillings for women from fetus through menopause because of this risk. Additionally, the FDA has recommended that children, people with neurological conditions such as multiple sclerosis, Alzheimer’s disease, or Parkinson’s disease, people with impaired kidney function, and people with increased sensitivity known (allergy) to mercury or other components of dental amalgam avoid having these mercury fillings placed.
“Toxic mercury vapors are continuously released from dental fillings with stimulation such as chewing,” explains david kennedy, DDS, former president of the IAOMT. “With Geiers’ new research joining the ranks of hundreds of other studies, it is abundantly clear that mercury from amalgam fillings poses a danger to everyone, including unborn babies, patients, dentists and caregivers. dental employees.”
Geiers’ study was partially funded by IAOMT, a nonprofit organization that evaluates the biocompatibility of dental products, including the risks of mercury fillers.
