Mercury-Free. Mercury-Safe. 

Our commitment to the health of our patients, our team, & our environment. 
“Adverse health effects from mercury exposure can be: tremors, impaired vision and hearing, paralysis, insomnia, emotional instability, developmental deficits during fetal development, and attention deficit and developmental delays during childhood. Recent studies suggest that mercury may have no threshold below which some adverse effects do not occur.” 
World Health Organization Policy Paper, 2005
  • “Mercury-free” is a term with a wide-range of implications, but it typically refers to dental practices that do not place dental mercury amalgam fillings.
  • “Mercury-safe” typically refers to dental practices that use rigorous safety measures to limit or prevent mercury exposure, such as in the case of removing previously existing dental mercury amalgam fillings and replacing them with non-mercury alternatives.

Human Health Risks from Dental Amalgam Mercury Fillings

All silver-colored fillings are dental amalgams, and each and every one of these fillings is comprised of 45%- 55% mercury. (2) Although a number of other countries have banned or limited their use, dental mercury amalgams are currently used on about 45% of direct dental restorations worldwide,(3) including in the USA. (4)

Silverfillings               silverfilling

Mercury is continuously emitted from amalgam fillings, and it is absorbed and retained in the body, particularly in the brain, kidney, liver, lung, and gastrointestinal tract. (5) The output of mercury can be intensified by the number of fillings and other activities, such as chewing, teeth-grinding, and the consumption of hot liquids. (6) Mercury is also known to be released during the placement, replacement, and removal of dental mercury amalgam fillings. (7)

Scientific studies have documented the potential risks these fillings pose to human health:
1) The General Population:

Mercury in amalgam fillings has been scientifically linked to a number of health conditions.  Individual response to mercury varies, and some of the factors known to potentially impact those exposed to mercury include their allergies, diet, gender, genetic predispositions to adverse reactions from mercury, the number of amalgam fillings in the mouth, and concurrent or previous exposures to other toxic chemicals such as lead (Pb). Scientific studies have identified dental mercury as a potentially causational or exacerbating factor in the following conditions:

Allergies, especially to mercury
Alzheimer's disease
Amyotrophic lateral sclerosis (Lou Gehrig's disease)
Antibiotic resistance
Autism spectrum disorders
Autoimmune disorders/ immunodeficiency
Cardiovascular problems
Chronic fatigue syndrome
Complaints of unclear causation
Hearing loss
Kidney Disease
Multiple sclerosis
Oral lichenoid reaction and oral lichen planus
Parkinson's disease
Periodontal disease
Psychological issues such as depression & anxiety
Reproductive dysfunction
Suicidal ideations
Symptoms of chronic mercury poisoning 
Thyroiditis


 
2) Pregnant Women and Children:

Scientific studies have documented the devastating impact mercury can have on pregnant women and children, and mercury from dental amalgam fillings in mothers has been recognized for its potential risk to fetuses and children who silver-fillings-are-toxicare being nursed. For example, higher numbers of maternal fillings have been correlated with higher levels of mercury in breast milk. Additionally, authors of a study from 2011 cautioned: “Changes in dental practices involving amalgam, especially for children, are highly recommended in order to avoid unnecessary exposure to Hg [mercury].”(8) For more information: Pregnancy, Children, & Dental Amalgam Mercury Fillings

3) Dentists and Dental Personnel:

Researchers have also demonstrated dangers to dental personnel who routinely work with amalgam, and the Norwegian Labour and Welfare Service has officially recognized mercury injury as an occupational disease. 4) Safe Removal of Existing Amalgam Fillings: Whereas “mercury-free” dentists no longer place amalgam fillings and use available alternatives, “mercury-safe” dentists apply special techniques to remove existing amalgam fillings. In fact, the IAOMT has developed rigorous recommendations for removing existing dental mercury amalgam fillings to assist in mitigating the potential negative outcomes of mercury exposure to patients, dental professionals, dental students, office staff, and others.(9)

 

Safe Mercury Amalgam Removal Technique (SMART)

The SMART technique was developed by the International Academy of Oral Medicine and Toxicology (IAOMT). The IAOMT is a trusted academy of allied professionals providing scientific resources to support new levels of integrity and safety in healthcare. SMART is a set of recommendations created by the IAOMT based on scientific research that includes pre-operative procedures to prepare body for removal of amalgam fillings, maximum protection protocols for patient, dental team, and environment, ventilation, biocompatible replacement materials, among other measures.
