The History of Dental Amalgam use and the Lies and Deception Used to Justify its Use

There has never been a time in U.S. History when mercury was not known to be extremely toxic and when 

there was credible evidence that use of dental amalgam is safe. There were medical/ dental studies from

the 1800s documenting significant exposures to mercury from amalgam and documenting harm to

patients from its use. The following compilation from dental journals of the 1800s such as the Ohio State

Journal of Dental Science includes over 880 pages of articles documenting that even from that time

dental authorities were aware that mercury was extremely toxic and that amalgam was not stable and use

of amalgam resulted in health harm including deaths. 

[Ohio State Journal of Dental Science from 1882 (harm from amalgam understood from the start of use)]

Due to the high toxicity of mercury and the known documented fact that those who have amalgam fillings

get significant mercury exposures and commonly experience adverse health effects, those dentists who

used mercury in dentistry were called Quacks, after the German word for mercury.


By the late 1900s there were thousands of peer-reviewed studies documenting high mercury exposures

from amalgam use, and common significant adverse health effects. (

and there are no credible studies suggesting amalgam use is safe and does not cause high mercury

exposures or common harm to people who use it. All that claim such have been refuted by experts.


Attached is an actual Ohio State Journal of Dental Science from 1882.  This has all the concerns that

were expressed about amalgams in 1882 (including leakage).  Eugene S. Talbot was an M.D and a

DDS.  It is approx. 882 pages! (includes discussion of history of amalgam use in U.S., beginning in 1833)


From its inception, the better class of dental practitioners waged war against its use . The manner in which it was introduced called forth the censure of all who have professional etiquette. “ page 2

Dr. Harris of the Baltimore College of Dental Surgery stated: “It is one of the most objectionable materials for filling teeth that can be employed” At the meetings of the dental societies the subject was discussed spiritedly with strong arguments against its use” They reported that such substances were hurtful to the mouth in all parts, and there was no caries in a tooth in which gold could not be employed. The report was unanimously adopted. Page 3


In 1845 the Mississippi Valley Association of Dental Surgeons resolved that the use of amalgam was injurious and unprofessional and would not be countenanced by its members. “ But the age of special interest distinformation campaigns by organizations such as the ADA promoting the use of amalgam due to its low cost and ease of use while disregarding the major health and environmental effects was begun and the negative reports and resolutions by the various societies did not stop the spread of amalgam use.

The rapidity with which the evaporation of mercury (from amalgam) takes place depends on the amount of heat and the surface exposed” The time required for substantial deposition of mercury using the ammonium-nitrate reagent of silver was 10 minutes. Many experiments were carried out, with results similar Page 6

The Dental Register of Dentistry, 1872, had the following case of poisoning from mercury in a tooth filling. “John T. Smith died from salivation, caused from mercury in a tooth filling” Dr. Sprague attended the case. Two other doctors consulted agreed he was suffering from the effects of mercury. It was clear that the mercury had caused his death. Page 7

Other cases of harm from amalgam cited, page 8, etc.


The reasons for the known high mercury exposures to all with several amalgam fillings due to mercury's unusual properties, are that gas is the only stable form of mercury at room temperature and “battery and EMF effects” pump mercury into the oral cavity and from there throughout the body (


Due to this, amalgam has been documented by thousands of tests by medical labs and confirmed by Government agencies to be the largest source of mercury in most people who have several amalgam fillings.


Due to mercury's properties and the high exposures of all who have several amalgam fillings or metal crowns over amalgam, dental amalgam is documented by Municipal Sewer Agencies and EPA to be the largest source of mercury in sewers and sewer sludge, with very high levels in both. The average person with several such amalgams or crowns over amalgams is documented to excrete approximately 30 micrograms per day of mercury into the sewers, a very high level since mercury is the most toxic element people commonly come into contact with. Medical labs found that the average person with amalgams excretes almost 10 times as much mercury as those without amalgams, and amalgam is a significant source of mercury in water bodies, the environment, fish, etc.

The known high environmental effects of mercury are one of the reasons some countries have banned amalgam use, such as Sweden and Norway ( and most other countries with modern medical systems have banned it use, or limited its use for women and children or require health warnings. Some U.S. states now also require health warning when amalgam is used. Yet special interest organizations who have benefited from amalgam use like the American Dental Association and Pharmaceutical companies that manufacture it have spent hundreds of millions on promoting its use and attempting to suppress the spread of accurate scientific knowledge about the high exposures and common harm caused by amalgam.
