The effect of occupational exposure to mercury vapour on the fertility of female dental assistants Exposure to mercury vapour or inorganic mercury compounds can impair fertility in laboratory animals. To study the effects of mercury vapour on fertility in women, eligibility questionnaires were sent to 7000 registered dental assistants. Detailed information was collected on mercury handling practices and the number of menstrual cycles without contraception it had taken them to become pregnant.
Karen Palmer, Mercury Poisoned Dental Assistant- 2006 FDA Testimony As a dental assistant I handled mercury every day for years until 2004 when I was diagnosed with heavy metal mercury poisoning. I am disabled and can no longer work due to the neurological damage from occupational exposure to mercury.
Karen Burns, Mercury Poisoned Dental Assistant - 2010 FDA Testimony Today I want to speak to the panel and urge them to help the FDA do their job. I testified at the FDA hearing in 2006, I watched the FDA panel vote 13-7, based on the fact that they could not prove amalgam was safe. I don't know what happened after that. It seems like they didn't do anything except make claims of safety without proof.  
Dr. Graeme Munro-Hall B.D.S mercury related heart problems and UNEP work Dr. Graeme Munro-Hall BDS discusses his mercury related heart problems and his work towards banning dental mercury amalgam by participating in the United Nations Environment Program (UNEP).

Dr. Janet Stopka D.D.S. shares her mercury toxicity story with FDA My name is Dr. Janet Stopka D.D.S.  I am a practicing dentist from Chicago.  I have not used mercury as a restorative material in 14 years and my patients are given informed consent.  No one has ever asked me to place mercury in their mouth and they understand immediately its toxic. But many of them don’t know they have it in their mouth!
Dental Amalgam Material Safety Data Sheets (MSDS) Overview The purpose of the MSDS is to protect workers by supplying them with the most crucial facts about the hazardous material at their jobsite, such as the physical properties of the material, proper storage and handling techniques, known health risks and essential emergency procedures.
IAOMT - Safe Removal of Mercury Amalgam Fillings - Video Dentists remove amalgam fillings every day, with no regard for the possible mercury exposure that can result from grinding them out.  The International Academy of Oral Medicine and Toxicology has established a mercury safe protocol that protects both staff and patients during amalgam removal.
Diane Meyer DDS Recovers from her debilitating health problems due to mercury toxicity In search of answers about her debilitating health problems, Diane Meyer, D.D.S., B.S., went from doctor to doctor and was told “It’s your hormones honey,”. Until she attended a seminar and learned of her constant exposure to mercury.
OSHA requires employers to provide a workplace free of serious recognized hazards and in compliance with OSHA Standards You have the right to a safe workplace. OSHA requires employers to provide a workplace that is free of serious recognized hazards and in compliance with OSHA Standards. David Kennedy shares stories of occupational exposure to mercury in the dental workplace. 
NIOSH - Criteria for a Recommended Standard Occupational Exposure to Inorganic Mercury The Occupational Safety and Health Act of 1970 created The National Institute for Occupational Safety and Health (NIOSH). NIOSH is an agency established to help assure safe and healthful working conditions for working men and women by providing research, information, education, and training in the field of occupational safety and health.
The Difference Between Mercury-Free and Mercury-Safe Dentistry Mercury free dentists have been known to polish and remove  "silver" amalgam fillings thereby exposing their patients and staff members to thousands of micrograms of mercury vapor and particulate matter. "Mercury Safe" dentists take every precaution to protect the patient, staff and environment from harmful mercury vapors and mercury contaminated particulate matter.
Mercury leaking from Kerr amalgam capsules during trituration Multiple federal service dental clinics have reported that mercury is released from Kerr amalgam capsules during trituration. Users have reported mercury in the mixing chambers of their triturators and have witnessed mercury ejection during trituration. The USAF Dental Investigation Service contacted The Kerr Corporation, who confirmed mercury is released from its capsules.
Mercury toxicity in the dental office: a neglected problem No longer can the dental profession ignore the problem of mercury contamination in the dental office. It is the moral responsibility that the dentist protect himself and his employees from any source that may be injurious to either his own physical well being or that of auxiliary personnel. It is also a legal responsibility under the enactment of the Occupational Safety and Health Act of 1970.
Affordable Dental Office Mercury Screening by Mercury Instruments USA With public concerns related to mercury becoming more common, it is essential to have a partner that you can trust with your mercury compliance needs. Mercury Instruments USA has made it affordable for you to easily prove and defend that your dental practice is compliant with the OSHA & NIOSH (REL) recommended exposure limits for mercury vapor in the workplace.
OSHA rebukes the American Dental Trade Association and reiterates encapsulated amalgam is a hazard that requires an MSDS OSHA has noted the American Dental Trade Association's (ADTA) position that Material Safety Data Sheets (MSDSs) fall within FDA's definition of labeling. As we have discussed in earlier meetings, this is unfounded.
Chronic neurobehavioural effects of elemental mercury in dentists A significant increase in aggressive mood measured by the profile of mood states was found between exposed and control groups. This increase in aggressive mood seemed to be related to dose, suggesting possible effects of exposure to mercury vapour on personality. 
Symptoms of Intoxication in Dentists Associated with Exposure to Low Levels of Mercury The present study examined the effects of occupational exposure of a group of dentists to low levels of mercury. Analysis of the data revealed that neuropsychological, muscular, respiratory, cardiovascular and dermal symptoms were more prevalent in dentists. Our findings indicate that occupational exposure of dentists to mercury, even at low levels, is associated with a significant increase in the prevalence of symptoms of intoxication.
Systemic mercury levels caused by inhaling mist during high-speed amalgam grinding This experiment has shown the following facts about the exposure of rats to an amalgam dust created by a high speed handpiece: 1.) The dust is almost immediately absorbed into the blood stream as shown by immediate increases detected by measuring the blood mercury content. 2. The heart receives extremely high levels of mercury within minutes after exposure. Eighty one times higher than the control level.
IAOMT Info-graphic - Occupational exposure to dental mercury The International Academy of Oral Medicine and Toxicology has released an info-graphic, Occupational Exposure to Dental Mercury,  that outlines the many ways in which occupational exposure to dental mercury occurs.
A Review of the ADA Mercury Hygiene Recommendations This article reviews and elaborates on the ADA’s 15-point mercury safety guidelines. Common workplace violations are highlighted, and steps for correction are cited. Practitioners can utilize this information to assist in development of an office protocol.

Dental Amalgam Material Safety Data Sheets (MSDS) Overview


The United States Occupational Safety and Health Administration (OSHA) requires the provision of a Material Safety Data Sheet (MSDS) for any hazardous material that poses a threat to employees in a workplace. The purpose of the MSDS is to protect workers by supplying them with the most crucial facts about the hazardous material at their jobsite, such as the physical properties of the material, proper storage and handling techniques, known health risks and essential emergency procedures.

Mike Flemming DDS, Advisor to the FDA (dental products panel 2006 & 2010) Explains The Dental Amalgam Material Safety Data Sheet - MSDS.

Mike Flemming DDS, Advisor to the FDA (dental products panel 2006 & 2010) Explains The Dental Amalgam Material Safety Data Sheet - MSDS.

Thus, manufacturers of amalgam fillings must create these information sheets, and their MSDSs include disturbing evidence about the known dangers of using mercury in dental fillings. Feel free to explore the sheets for yourself since we have provided you with the MSDSs from manufacturers of dental amalgam all over the world.  Here are a few highlights:

From Kerr Contour (CA, USA) and others…

“This product contains mercury, a chemical known to the State of California to cause birth defects or other reproductive harm.”

From Ana 90 Duett (Sweden)…

“Mercury may accumulate in the body which may cause adverse health effects.”

From Kerr Sybraloy (CA, USA) and others…

“Mercury should not be allowed to enter sewers.”

From Goldsmith (NJ, USA)…

“Repeated low exposure or very high single exposure can cause Mercury poisoning.  Symptoms include tremors (shaking), trouble remembering and concentrating, gum problems, increased salivation, loss of appetite and weight, and changes in mood or personality.”“Mercury may lower sex drive.”

From Ivoclar Vivadent (NY, USA)…

“Mercury can cause urinary problems, visual disturbances, tremors, salivation, stomatitis, loss of teeth, blue lines on gums or neurotoxic/nephrotoxic effects.”“Do not touch spilled mercury.  Collect the mercury droplets using specialized mercury vacuum cleaner.”

From Original D Wykle (NV, USA)…

“Separate work and street clothing.  Store work clothing in special lockers.  Showers to be taken before chaning (sic) into street clothes.  Provide pre-placement and periodic medical exams for those regularly exposed to mercury with emphasis directed to CNS-central nervous system, skin, lungs, liver, kidneys, and G.I. tract.”

From Oralloy MagiCaps (Switzerland)…

“Mercury: Poison by inhalation.  Human gastrointestinal tract and central nervous effects.”

From Bethlehem Apparatus Company (PA, USA)…

“Mercury is highly toxic, irritating and causes sensitization and neurological symptoms.”“Mercury causes severe, adverse health effects after chronic exposure to low vapor levels.  Emergency response efforts must be directed to removal of all traces of this product.”“The principal target organ associated with chronic Mercury exposure via inhalation is the central nervous system.  Such exposures lead to the development of “Erethism.”  This syndrome consists of subtle or dramatic changes in behavior or personality: depression, fearfulness, restlessness, irritability, timidity, and indecision. These psychic and behavioral characteristics are often accompanied by insomnia, drowsiness, headache, fatigue.  In advanced cases, memory loss, hallucinations, and mental deterioration may occur.”“This product is reported to cause reproductive effects in humans.  Impotence has been reported in over-exposed males.  Women occupationally exposed have reported menstrual disturbances, reduced ovulation, and spontaneous abortions.  Mercury is excreted in breast milk.”Pre-existing respiratory problems, dermatitis, central nervous system disorders, kidney problems, and liver dysfunction can be aggravated by exposure to this product.”“Mercury can be harmful or fatal to contaminated plant or animal life.”

From Ivensys (MA, USA)…

“Chronic exposure appears more common than acute and is primarily associated with central nervous system damage which can be permanent (ex. paresthesia of the hands, lips, feet).  Early signs of toxicity include weakness, fatigue, anorexia, weight loss, and gastrointestinal disturbances.  If exposure levels are high, characteristic tremors of the fingers, eyelids, and lips occur with progression to generalized tremors of the entire body.  Psychic disorders are noticeable and characterized by behavior and personality changes, increased excitability, memory loss, and depression.”

From Schein (England)…

“To promote safe handling, each customer or recipient should (1) notify its employees, agents, contractors, and others whom it knows or believes will use this material of information regarding hazards or safety (2) furnish this same information to each of its customers for the product and (3) request its customers to notify their employees, customers, and other users of the product of this information.”

From SDI (Australia)…

“Toxic by inhalation.”

From SILMET (Israel)…

“The number of amalgam restorations for one patient should be kept to a minimum.”

From Caulk - Disperalloy (USA)

The use of amalgam is CONTRAINDICATION, which means that their material"should not be used in the following circumstances".

  • In proximal or occlusal contact to dissimilar metal restorations.
  • In patients with severe renal deficiency.
  • In patients with known allergies to amalgam.
  • For retrograde or endodontic filling.
  • As a filling material for cast crown.
  • In children 6 and under.
  • In expectant mothers.

Mercury expressed during condensation and unset amalgam may cause amalgamation or galvanic effect if in contact with other metal restorations. If symptoms persist, the amalgam should be replaced by a different material. Removal of clinically acceptable amalgam restorations should be avoided to minimize mercury exposure, especially in expectant mothers.

Precautions:;The number of amalgam restorations for one patient should be kept to a minimum. Inhalation of mercury vapor by dental staff may be avoided by proper handling of the amalgam, the use of masks, along with adequate ventilation. Avoid contact with skin and wear safety glasses and gloves. Store amalgam scrap in well sealed containers. Regulations for disposal must be observed.
