Mercury is retrograde

Hydrargyrum (Hg), more commonly known as quicksilver or mercury, is one of the most toxic elements on earth. Exquisite to behold when flowing around Alexander Calder’s Mercury Fountain in Barcelona, it’s not quite so beautiful when residing two inches from your brain.

The phrase ‘mad as a hatter’ directly describes the mercury-induced psychological and neurological ills that beset hat makers who used mercury solution to stiffen felt. Nowadays, industrial materials, grain fungicides, contaminated fish and ‘silver’ amalgam fillings can all cause mercury poisoning.

Chronic mercury toxicity can cause a bewildering array of symptoms that doctors often attribute to other causes. The variety of symptoms depends (a) on which organs have been affected by mercury poisoning and (b) on the affected person’s inherent weaknesses. Typical problems include diminished short-term memory, brain fog, left-sided migraines, depression, candida, skin that is grey, rough or red, hostility and an angry temperament (mercurial, perhaps…?). Symptoms of mercury poisoning have at times been diagnosed as Alzheimer’s, MS and myasthenia gravis, among other serious illnesses.

Many of us have reclined stiffly in our dentist’s chair while the white-coated one has filled our teeth with squeaky globs of amalgam. Cheap, durable and easy to insert, silver amalgam is a mélange of mercury, silver, tin and other metals. It has been used in dental restoration for over 100 years, in spite of both initial and more recent concerns as to its safety.

Dental schools have long taught that once mercury is bound with other metals in ‘silver’ amalgam, it is relatively stable and unlikely to cause health problems when placed in the mouth. But more recent research findings dispute that claim and argue that highly toxic mercury vapour leaches from amalgam fillings with relative ease. It only takes a bit of chewing, brushing, tooth grinding or knocking back a few hot coffees to encourage it to flow. And if you consider that a euphemistically named ‘silver’ amalgam filling typically contains over 50% mercury at time of placement, that’s a lot of vapour to go round. Perhaps they should be called quicksilver amalgam fillings instead.

Amalgam is so toxic that manufacturers and dentists treat it as hazardous waste when creating, placing and disposing of it. It is not, however, considered hazardous waste in your mouth! Once in situ and subjected to daily heat and abrasion, advocates of amalgam regard it as relatively harmless.

Does that make any sense?

The Swedish and Norwegian governments think not. They have banned the use of amalgam in dentistry as unacceptably unsafe, especially when healthier alternatives are now available.

If you suffer myriad (or even a few) inexplicable but worrying health problems, it may be worth researching the issue of dental amalgam. If you decide to have your fillings removed, it is imperative that you choose a dentist who knows his or her stuff. Amalgam removal is highly specialised. Incomplete or careless work can cause an increased intake of mercury vapour, making matters a lot worse.

A nice little twist: according to, the word ‘quack’ originated during the Renaissance when quicksilver was a popular remedy for syphilis. Wandering peddlers, known as ‘quacksalvers’, sold mercury ointment with the claim that it would cure all ills. The term was later shortened to ‘quacks’ and quacks became a symbol of evil medical practice.
