Understanding the Risks of Mercury from Amalgam Fillings
Research conducted by Clarkson (1998) and supported by the World Health Organization (WHO) has demonstrated that a single silver amalgam filling may release between 3 to 18 micrograms of mercury per day. By contrast, health authorities such as a Canadian regulatory conference have suggested a Tolerable Daily Intake (TDI) of only 1 microgram per day for a person weighing approximately 150 pounds. This means that individuals with more than two or three amalgam fillings may exceed safe daily exposure levels for mercury.
Further evidence from Dr. Mark Richardson of Ottawa, Canada, confirmed that individuals with more than three amalgam fillings are exposed to levels of mercury comparable to occupational exposure. In other words, these fillings can emit as much mercury as one might encounter working daily in an environment where mercury is present.
At MedPlex Dental Holistic Dentistry, our holistic dentist and team are committed to educating patients about these risks and offering mercury-free, non-toxic dental treatment options in Orlando, FL.
How Mercury Affects the Body: Mechanisms of Toxicity
Calcium Disruption and Vitamin D Metabolism
Mercury interferes with calcium balance in the body, contributing to concerns such as osteoporosis. The liver and kidneys—organs commonly affected by mercury—are essential in activating vitamin D, which plays a vital role in calcium absorption and bone health. Impairment in this system may reduce the body’s ability to properly utilize calcium.
Oxidative Stress and Cellular Damage
Mercury exposure leads to the formation of free radicals, which cause oxidative stress. This results in damage to cell membranes and other cellular components, undermining tissue health and resilience.
Energy Production Interference
Mercury can block the biochemical pathways needed to regenerate adenosine triphosphate (ATP), the body’s main energy molecule. This interference may explain the chronic fatigue reported by individuals with mercury exposure, as the body struggles to maintain its energy cycle.
Kidney and Neurological Impact
Mercury toxicity has been linked to protein leakage and cell damage in the kidneys. According to WHO (1991), urinary mercury levels above 100 micrograms per gram of creatinine significantly increase the risk for neurological disorders and kidney impairment, even in individuals with only a few amalgam fillings.
Immune Suppression and Autoimmunity
Studies from Europe and other global research bodies have shown that mercury may reduce the effectiveness of white blood cells, leading to immune suppression. It has also been implicated in autoimmune diseases including arthritis, lupus and potentially multiple sclerosis.
Pregnancy and Developmental Risks
Mercury can cross the placental barrier. Research by Marsh et al. (1981, 1987) showed that high levels of maternal hair mercury during pregnancy were linked to a significantly increased risk of psychomotor and neurological issues in infants. Even low levels between 10 to 20 micrograms per gram have been associated with developmental risk (WHO, 1990).
At our practice, we take these findings seriously. Dr. Roberto Castellini offers mercury-free dentistry to help reduce long-term health risks and support total-body wellness. Call 407-351-2245 to learn more about your options for safe, toxin-free dental care in Orlando, Florida.
Frequently Asked Questions About Mechanisms of Toxicity
Can one or two amalgam fillings really cause health problems?
Yes, even a small number of amalgam fillings can release low levels of mercury vapor daily. While some people may not experience immediate symptoms, others – especially those who are sensitive or have compromised detoxification systems – may be more affected over time.
How does mercury from fillings enter the body?
Mercury vapor is released during chewing, brushing or grinding teeth. It can be absorbed through the lungs and enter the bloodstream, where it may accumulate in tissues, including the brain, kidneys and liver. Our holistic dentist and team use certified protocols to safely remove amalgams and limit exposure.
Is there a safe way to remove amalgam fillings?
Yes. At MedPlex Dental Holistic Dentistry, we follow strict safety guidelines for mercury removal, including protective barriers, high-volume suction and oxygen for patients. These protocols reduce mercury exposure during the procedure and protect both patients and our dental team.
Can mercury fillings affect children or pregnant women differently?
Mercury exposure poses greater risks to developing systems. It can cross the placenta and affect fetal development. Children are also more vulnerable due to their smaller body mass and ongoing growth. That is why our holistic dentist recommends mercury-free alternatives for safer, long-term care.
