In 1833 the Crawcour brothers, two Frenchmen, brought amalgam to the United States, and in 1844 it was reported that fifty percent of all dental restorations placed in upstate New York consisted of amalgam.[5] However, at that point the use of dental amalgam was declared to be malpractice, and the American Society of Dental Surgeons (ASDS), the only US dental association at the time, forced all of its members to sign a pledge to abstain from using the Mercury fillings.[6] This was the beginning of what are known as the first dental amalgam war.[7] - excerpt wikipedia.

Why is mercury used in fillings?
Dental amalgam is an acceptable material for dental fillings. It lasts a long time (15-20 years), it is very affordable, and it is easy to use. On the down side, amalgam is not cosmetic, and eventually all amalgam fillings fail and must be replaced. There are more modern materials that can be matched to the color of the tooth being filled. Some dentists have expressed concern over the possible toxic effects of mercury leaking from the amalgam. However, considering the BILLIONS of amalgam fillings that have been placed over the past century, it has not been scientifically established that amalgam poses a significant health threat. Nevertheless, you can find several websites that trumpet the horrors of alleged mercury poisoning from amalgam fillings. On a personal note, it has been my experience that dentists who encourage patients to remove all their amalgam fillings and replace them with 'non-toxic' fillings are looking to line their own pockets with gold. If a filling is clearly failing, that is one thing, but to remove a perfectly functioning amalgam (and remove more tooth structure in the process) is, in my opinion, irresponsible and unethical. Today, many dental offices are 'mercury-free'. and that is fine. As the costs of alternative materials come down, eventually amalgam fillings will simply be a quaint sidebar in the history books of dentistry.
What are Amalgams?
Amalgams are a type of material used in dentistry to fill cavities. They are made from a combination of metals such as silver, tin, copper, and mercury. Amalgam fillings have been used for many years due to their durability and strength.
What element is used to make amalgam?

What are the symptoms of aluminum poisoning?
It has never been demonstrated that there any such thing as 'amalgam poisoning'. In extremely rare cases, people have been shown to be allergic to one or more components of amalgam, but that is not the same as amalgam poisoning.There are numerous websites and publications that try to make the claim that amalgam is toxic and dangerous. Nevertheless, the empirical evidence indicates amalgam fillings are extremely safe and adequate as dental restorations.Consider this: Over the past 150 years, there have literally been billions of amalgam fillings placed in hundreds of millions of teeth in hundreds of millions of mouths throughout the world. If there was a significant health risk associated with amalgam fillings, it would have shown up by now at least in the millions. This simply is not the case.If amalgam fillings were the cause of even half of what many people claim, it would be simple enough to demonstrate. All that would have to be done is collect health data on a few thousand people who have amalgam fillings. Then do the same with a few thousand people who have never had amalgam fillings. Then compare the data from the two groups. After allowing for age, sex, race, geography, and nutrition, if amalgam fillings are responsible for anything from Alzheimer's to Aids to Zebra stripes, it will show up clearly in the amalgam group and not in the control group. If not, then amalgam fillings are not the culprit.Take the advice of Consumers Union who did an in-depth investigation into the claims that amalgam fillings were dangerous: If a dentist tells you all your amalgam fillings need to be replaced due to toxicity or some obscure medical condition, hold on to your wallet. The dentist is trying to line his pockets with gold. An "amalgam" is made from mercury mixed with other metals (silver, zinc, etc), and mercury poisoning is not all that rare. If something has been used over 150 years, those that use it are not going to be extremely willing to change. If your dentist suggests you replace your fillings, but all means consult other experts, but include a medical doctor. You may be one of those 'rare' persons whose exposure to even a small amount of mercury is a serious health risk.
What is the prevelamce of mercury poisoning from dental fillings?
"Mercury poisoning" is an imprecise term that can apply to numerous symptoms associated with absorption of mercury. According to the FDA: "FDA has reviewed the best available scientific evidence to determine whether the low levels of mercury vapor associated with dental amalgam fillings are a cause for concern. Based on this evidence, FDA considers dental amalgam fillings safe for adults and children ages 6 and above. The amount of mercury measured in the bodies of people with dental amalgam fillings is well below levels associated with adverse health effects. Even in adults and children ages 6 and above who have fifteen or more amalgam surfaces, mercury exposure due to dental amalgam fillings has been found to be far below the lowest levels associated with harm. Clinical studies in adults and children ages 6 and above have also found no link between dental amalgam fillings and health problems."
