Are Your Teeth Toxic?

As many as 180 million Americans have more than a half billion teeth restored with fillings made with mercury amalgam.* Dental amalgam is a mixture of metals, consisting of liquid mercury and a powdered alloy composed of silver, tin, and copper. About 50% of an amalgam filling is elemental mercury. Why is this filling material potentially dangerous to your health?

History of Mercury Amalgam Fillings

Mercury amalgams (known in slang as “quick silver”) were invented in England in the early 1800s as an illegal black market product. Interestingly, the Germans called this product“Quack Silber” and from this pronunciation dentists throughout Europe using amalgam fillings came to be known as “quacks”.  A word that we associate today with doctors using unproven or questionable procedures.


In the early 1800s American dentists were instructed by The American Society of Dental Surgeons not to use mercury-based amalgam fillings because they considered mercury a toxic health hazard.  Unfortunately, the only alternative materials were very expensive and technically difficult.

At that time anyone could hang out a shingle as a dentist and there were fewer than 300 actually “trained” dentists across America. Many of these “untrained dentists” started using mercury amalgam because of its low costs and simplicity of use.

In 1856 the newly formed American Dental Association claimed that mercury fillings were safe and that dentists who said otherwise were “unethical”. As our opening statement shows, mercury amalgam had become the material most commonly used for fillings for decades and until the late 1990’s we had very few alternatives. Today composites and porcelain are definitely superior alternatives, but some short-sighted insurance companies will still only pay for the cheaper mercury amalgam fillings.

Why We Are Mercury Free

According to the FDA the elemental mercury in dental amalgam releases low levels of mercury in the form of vapor that can be inhaled and absorbed by the lungs. High levels of mercury vapor exposure are associated with adverse effects on the brain and the kidneys.
