What are dental amalgam fillings?

Dental amalgam is one of the first ancient and golden standard filling materials that has been used for over 150 years, and it is still used to fill dental cavities caused by tooth decay or tooth fracture. If your dentistry is not mercury-free, your dentist mixes will use a prepared capsule in which liquid (elemental) mercury is mixed (amalgamated) with powdered silver, copper, and tin compounds. The fillings will be inserted in your cavity in portions and condensed before setting and carving. Once the mercury amalgam mixture hardens, it forms a strong, solid, silver filling.

Mercury is a chemical naturally occurring in rocks, including the earth’s crust. It exists in three chemical forms:

Elemental Mercury

This is the metallic liquid form of mercury, which is often used in barometers, fluorescent lights, and some light switches.

Inorganic Mercury

These compounds enter the environment through coal burning or manufacturing processes. People working in mines or manufacturing electrical equipment are exposed to higher levels of inorganic compounds. Sadly, some skin-lightening facial creams or lipsticks may also contain these mercury compounds.

Methylmercury

These organic compounds are found to a high content in seafood, fish, and shellfish.

Elemental mercury

Elemental mercury used in dental amalgams is a liquid metal that appears silvery-white at room temperature.

While being safe in a contained form such as a thermometer or barometer, mercury evaporates into a toxic, odourless vapour you could inhale when exposed to room temperature air.

As dental amalgam fillings contain elemental mercury up to 50% by weight, hundreds of clinical studies have associated a few adverse health effects with dental amalgam, including thyroid dysfunction.

Both laboratory and clinical studies have demonstrated increased mercury leakage digestion and vapour inhalation from the amalgam fillings during brushing, chewing, or teeth grinding.

Surprisingly, the Environmental Protection Agency (EPA) consider these estimated quantities of amalgam exposure to be within the safe!

Short or long-term exposure to elemental mercury can be biologically very harmful and cause symptoms such as memory decline and cognitive problems, emotional changes, headaches, neurological disorders, tremors and sleeping disorders.

On the other hand, specific individuals could be at greater risk of the biological adverse effects of mercury exposure, including pregnant women, nursing women and their infants, children under the age of six, individuals with a sensitivity to mercury or other components of dental amalgam, people with kidney impairment and patients with neurological disorders.

Is there a home test for mercury poisoning?

Home mercury poisoning tests are available with instructions, or you can have a home nurse take a blood sample. Typically, mercury is found in the body at harmless levels from daily exposure to sources like seafood, certain cosmetics, and dental amalgam, which emit mercury vapour. High exposure to elemental mercury vapour from items like thermometers and lightbulbs can cause neurotoxic effects, especially in the brain and central nervous system. The World Health Organisation notes that behavioural changes can follow inhalation of various mercury compounds.
Health impacts from mercury depend on the amount and type ingested and individual factors like age and pregnancy. Teeth grinding can elevate mercury risks from fillings due to increased pressure. Methylmercury exposure is particularly hazardous for children and foetuses with developing nervous systems.
Symptoms that may prompt mercury testing include memory issues, metallic taste, abdominal pain, sleeplessness, numbness, involuntary eye tremors, dizziness, hearing loss, unclear speech, depression, coordination problems, fatigue, and restless legs.

What are the health hazards of Amalgam Fillings for pregnant women and children?

Mercury exposure from dental amalgam fillings is a significant health concern, especially for pregnant women and children. A World Health Organisation report from 2005 detailed the potential for serious health problems due to mercury, such as developmental issues and neurological damage. International warnings and actions from U.S. Congress members, including a proposed but not enacted Mercury Filling Disclosure and Prohibition Act, highlight the risks to vulnerable populations.
Research indicates that the number of amalgam fillings in pregnant women correlates with higher mercury levels in various foetal and infant tissues and breast milk. This exposure has been associated with an increased risk of perinatal death, as found in a Norwegian study of over 72,000 pregnant women. While some studies have defended amalgam use, others have pointed out the necessity of considering long-term effects, genetic factors, and potential measurement errors.

Criticism of amalgam use is underpinned by the fact that children, due to their smaller size and developmental stage, may require different safety thresholds for mercury exposure.

Considering these findings, a recent study strongly recommends revising dental practices involving amalgam to prevent unnecessary mercury exposure, particularly in children, reaffirming the ongoing concerns within the scientific community.

How do we assess and Manage the Biological Risks of Mercury Exposure?

Mercury is a toxic metal in various environmental forms. Mercury poisoning, caused by high mercury intake, can arise from sources like dental amalgam fillings and seafood containing methylmercury. Healthcare providers commonly use urine, blood, and faecal tests to diagnose mercury poisoning.

Urine mercury tests detect inorganic mercury, with levels under 10 mcg/L considered normal. High urine mercury levels might indicate a need for detoxification. Faecal tests measure exposure to dietary toxic metals and can reflect the number of dental amalgam fillings. Blood tests reveal recent mercury exposure but are less reliable over time as mercury levels in blood decrease quickly.

Symptoms of acute mercury poisoning include nausea, diarrhoea, and an increased heart rate. Treatment is necessary when tests indicate mercury toxicity. This article aims to inform about the testing methods for mercury poisoning from dental fillings, highlighting urine and blood tests as the most effective.

How to minimise and counteract mercury toxicity

Please take these steps: Limit intake of high-mercury fish such as bluefin tuna and swordfish, and opt for lower-mercury seafood like haddock, salmon, sardines, and scallops, using resources like Seafood Selector for guidance. The FDA advises pregnant women to avoid certain high-mercury fish. Support your liver’s detox function by consuming foods rich in alkaline, B12, folate, and liver-friendly nutrients, with cilantro notably beneficial against heavy metals. Some supplements, such as selenium, can mitigate mercury’s adverse health effects. If you’re considering mercury filling removal, you’d need a dentist skilled in the SMART technique to discuss safe amalgam removal and suitable replacement materials. At Rejuvenation Dentistry, our biological dentists understand the systemic influence of oral health and can guide you through amalgam filling replacement to enhance your overall well-being.

Is there any association between Dental Amalgam Fillings and hypothyroidism?

Heavy metal exposure has been suggested to be the potential trigger and exacerbate autoimmune conditions in genetically predisposed individuals. Studies show that amalgam mercury can accumulate in thyroid cells and cause thyroid disorders by:

  1. Changing the genetic makeup

    Hence causation of certain types of cancer, including thyroid cancer.
    It also could lead to a Thyroid autoimmune disorder called Hashimoto’s thyroiditis. The autoimmune reactions caused by a high level of mercury would promote triggering our immune system, which in turn would destroy our own healthy cells, including our thyroid cells, the condition called Hashimoto’s thyroiditis.

  2. Raising the oxygen free radical levels

    The research shows that when the balance between the beneficial antioxidants and harmful free radicals is changed, the emergence of Oxidative stress, and in turn, the resulting chronic inflammation may contribute to an increased risk of thyroid under-activity, including Hashimoto’s thyroiditis.

  3. Binding of dietary mercury to Selenium

    Hence reduced selenium. This would lead to selenium deficiency.

As a result, we may experience symptoms caused by hypothyroidism, including the following: Cold intolerance, constipation, dry skin, fatigue, joint pain, mental health changes or mood swings, muscle weakness and insomnia.
