Dentists’ Dirty Little Secret

Dear Beauty Conscious Reader,

It’s a well-known fact that mercury is toxic. It’s also a fact that “silver” amalgam fillings in your teeth contain mercury.

When the mercury escapes from your fillings and into your bloodstream, a lot of serious health problems can result. Sleep disturbances, memory loss, muscle weakness, high blood pressure, rapid heartbeat, and swelling… just to name a few.

But here’s something you probably would never realize…

Mercury toxicity can also give you skin rashes, discolored fingernails, and make your hair fall out.

According to the Environmental Protection Agency (EPA), the amount of mercury in a single, typical “silver” filling placed in a 10-acre lake would be enough for them to classify the entire lake as toxic.

Yet, the American Dental Association (ADA) insists that mercury fillings are safe. They claim mercury amalgams are a problem only for those sensitive to mercury. Their “proof” is that these fillings have been used for 150 years.

The problem is that chewing releases trace amounts of mercury from fillings into your mouth – with every bite. So can grinding your teeth and drinking hot liquids. And old fillings are prone to corrosion by acidic foods or saliva.

That kind of constant, low-level exposure builds up over time. Many adults have fillings from childhood that fit this risk profile.

So, should you have your mercury fillings removed? You should probably consider replacement if:

You have any of the above symptoms that have not responded to treatment.

  • You have many old silver fillings.
  • You grind your teeth.
  • You drink hot coffee or tea.

If you do decide to have your silver fillings removed, limiting the amount of mercury vapor emitted during removal is key. Be sure to choose a dentist who is practiced specifically in mercury amalgam removal. Someone who is well-informed about the toxicity danger and who will take the necessary precautions during your office visit. Make sure you ask about these procedures before you begin.

And don’t rush it. Too many removed at one time can also expose you to excess levels of mercury. This is exactly what you don’t want. Remove your fillings judiciously – a few at a time. Space your appointments several weeks apart.

For any new fillings, you should insist on one of the non-mercury alternatives. There are new materials available that are safe. The best are bonded resin ceramics.

Mercury proponents insist that their bonding ability is much lower than that of traditional silver amalgams. But what you trade off in bonding ability, you make up for in biocompatibility. They are tooth colored, so your smile will look better too.

To Your Good Health,
