Other than radioactive elements, mercury is the most toxic, naturally-occurring substance on Earth. There is no safe level of mercury in your body, according to the World Health Organization (WHO).

Yet it might be in your teeth, and the person who put it there is a doctor – your dentist. Mercury is a key element of the filling a dentist uses on your cavities.

What’s worse, the dental industry deceptively calls it a silver filling, even though mercury comprises more than half of the amalgam by weight.

Consider this: the Environmental Protection Agency requires that mercury, and other materials in your filling, be placed in a hazardous waste container when removed from your tooth. But there is nothing regulating how much mercury can be placed in your mouth in the first place.

Mercury poisoning can be fatal
How bad is mercury for you? Mercury is a neurotoxin – it poisons nerve tissue.

Mercury vapor that seeps out of your teeth into your body has been linked to autoimmune issues, and just about every disease and health condition that affect people every day. Norway, Sweden and Denmark have banned mercury fillings.

Megan’s mercury adventure
In my book, Stop the Snore: Dental Solutions for Healthy Sleep, I document the story of a patient named Megan, who developed hives and difficulty sleeping shortly after receiving a vaccination. A naturopathic physician suspected that the vaccination, which contained mercury, added to the mercury-based fillings already in her mouth, was overwhelming her immune system and causing her symptoms.

After a series of tests, we determined that Megan had high levels of mercury in her mouth and her bloodstream. We replaced the fillings in three teeth with the biocompatible composite restorations and her hives immediately disappeared.


The mercury was clearly the culprit.


But it gets better. Because the inflammation that Megan experienced from what was essentially mercury poisoning immediately subsided, Megan’s air passages opened up when she slept. The very next night she experienced the deep, restful sleep that had eluded her since the vaccination.


You may be thinking that everyone you know has cavities filled with amalgam composed of mercury and they seem to be doing all right.

Of course, your symptoms depend on how much mercury is in your mouth, for how long, and other variables about your health and lifestyle, including your genetics. The effects are cumulative over time because the mercury remains in your teeth every day, leaching out little by little. People who smoke cigarettes don’t generally see the effects for decades, but we know that smoking kills people.


Based on what we’ve learned about the harmful effects of mercury fillings, I long ago stopped offering them to my patients over 25 years ago. I hope all dentists decide to do the same.
