Dentistry claims that it is safe to implant one of the most toxic substances known to science
into living human beings – Dentistry claims that mercury amalgam is safe and effective.
What IS a Little BIT of Mercury?
Criteria 118 World Health Organisation 1991
The No Observable Effects Level (NOEL) for mercury is ZERO
There is NO safe level of mercury vapour
On 7 January 2003, the Superior Court in San Francisco
approved the warnings on dental amalgam mercury
that are required under California's Proposition 65
Warning on dental amalgam, used in many dental fillings,
causes exposure to mercury,
a chemical known to the state of California to cause
birth defects or other reproductive harm.
Swedish Government report of 2003 states:
"With reference to the fact that mercury is a multipotent toxin
with effects on several levels
of the biochemical dynamics of the cell,
amalgam must be considered to be an unsuitable material
for dental restoration.
This is especially true since fully adequate and
less toxic alternatives are available."
http://www.robertgammal.com/AmalgamDocs/SwedishGovtReport.htmlThe dental associations and even government bodies tell us that amalgam is safe because only a 'little bit' of mercury comes out of amalgam fillings. They support this comment by telling us that most of the mercury comes out at the time of amalgam placement, thus insinuate that it is OK once the amalgam is set.
The fact is that mercury is released from amalgam throughout the life of the filling.
In 1996 Dr Richard S. Tobin, Ph.D, then the Director of the Medical Devices Bureau, Canada Health, wrote to the Canadian Dental Association, in response to their position statement on dental amalgam and a set of questions and answers on amalgam to be used by dentists in responding to inquiries from patients.

Canadian Dental Association:
Q. Is the mercury which is released from fillings absorbed into the body?
A. Yes, but in extremely small amounts, i.e. in MILLIONTHS of a gram (this is very small amount, 0.000001 grams.)
Dr Tobin's Response:
"This answer is rather condescending and insulting to the intelligence of readers. By emphasizing only how small a microgram is it implies that a microgram of toxic material could not be harmful. What is significant is not now many zeroes there are in a microgram, but how many micrograms of mercury are released by and compared to the number of micrograms required to cause illness. The fact is that a level of only one hundred millionths of a gram (only 0.0001 gram) of mercury per gram of Creatinine in urine is considered to indicate clinical mercury poisoning."
The latest NH&MRC statement on dental amalgam uses the same nonsensical argument to support the continued poisoning of the population - "Very small amounts of mercury are released from the surface of dental amalgam fillings, mainly as mercury vapour. ....In this way, some mercury can reach the rest of the body and accumulate in certain organs, particularly the kidneys"
OSHA in America and Australia, has set the maximum allowable mercury vapour levels for occupational exposure based on a 40 hour/week exposure at 50mcg Hg/m3. If this level is exceeded the work place must be closed down. Everyone else is under the jurisdiction of the US EPA who have set a maximum level of 0.2mcg Hg/m3. The Agency for Toxic Substances and Disease Registry which is part of the US EPA have agreed with the maximum level set by the EPA but also state that observable physiological changes will occur at levels as low as 0.03mcg Hg/m3.
Check these figures - numbers represent micrograms per cubic meter of air
OSHA - Occupational Safety & Health Association 50 mcg/m3
US Environmental Protection Agency 0.2 mcg/m3
Agency Toxic Substances & Disease Registry 0.03 mcg/m3
NOEL - No Observable Effects Level set by WHO 1991 0
In a mouth with 6 amalgam fillings 20-120 mcg/m3
Opening a mixed amalgam capsule 1000 mcg/m3
Drilling amalgam fillings - 18 inches from the mouth 4000 mcg/m3
"The number of amalgam fillings, for each age group, estimated to cause exposure equivalent to the TDI were: 1 filling in toddlers; 1 filling in children; 3 fillings in teens; and 4 fillings in adults and seniors."
(ASSESMENT OF MERCURY EXPOSURE AND RISKS FROM DENTAL AMALGAM by G. Mark Richardson PhD., Medical Devices Bureau, Environmental Health Directorate, Health Canada Executive Summary.) - (adopted by Health Canada in 1996)
Most adults and children throughout the world have far more than 4 amalgam implants! Mercury vapour levels in mouths with half a dozen amalgams have been measured up to 120mcg Hg/m3.
Dental personnel (and patients) should NOTE that levels of mercury vapour from dental amalgam (placing, drilling and polishing) within the dental environment will often exceed the level set by OSHA of 50 mcg/m3.
All patients should ensure that their dentist does NOT use amalgam and that the suction units from all operatories must be vented to the outside of the building.
Keep away from amalgam! The vapour levels are beyond belief! See the Warnings about Amalgam Removal and also the paper about the health of dentists and dental personnel.
There is not a country anywhere which has found a safe level of mercury vapour and thus the 'NOEL' or 'No Observable Effects Level' is still set at 0 mcg Hg/m3.
In other words there is NO safe level of mercury vapour!
