According to the United States Department of Labor, there
were 200,500 dental hygienist jobs in this country in 2014, with a growth
outlook of 19 percent (much higher than most fields) in the next ten years.
There are even more dental assistants at 318,800, with an 18 percent growth
outlook. Nearly 96 percent of those dental workers are female. Many are young
women, starting families. As a holistic dentist in NY, I am concerned about
the potential of mercury dental fillings to cause these individuals grave health
problems, including birth defects and reproductive failure.
Occupational hazards of amalgam fillings
Silver-colored fillings contain about 50 percent elemental
mercury, a known neurotoxin. In conventional dental offices, dental workers
rarely wear protective gear or use air filtration masks. The rationale given by
their employers is usually two-fold. First, since the ADA and FDA have long
supported use of dental amalgam, it must not be dangerous. Second, protective
gear would scare patients on the receiving end of amalgam fillings. Most dental
workers aren’t fully aware of the hazards of working with amalgam, and their
health suffers as a result.
How mercury infiltrates the body
Elemental mercury can be absorbed through the skin,
ingested, or inhaled. Dental workers are commonly exposed to mercury vapor.
They work in close proximity to a patient’s mouth, breathing the vapor each
time an amalgam filling is polished, ground, or drilled.
The human body has no way to flush mercury, so it builds up
over time. Mercury vapor attacks the central nervous system, and impairs lung
and kidney function. Because the toxin crosses the placenta, it also
accumulates in unborn babies. Fetuses are especially susceptible,
as the neurological system is developing.
There way to resolve this
very real health threat to thousands of NY dental workers and their future
offspring. The change will occur when dentists, dental support staff, and patients
demand a healthier alternative to mercury-laden amalgam fillings.
