One way they could ban it is to follow some European countries who have banned it either on a precautionary side or as an environmental issue.

I think that here in the UK a lot of dentists are avoiding amalgams. Every dentist here in my town used them 10 years ago, but now they seem to be in the minority. Even my old dentist now has left the NHS and no longer uses amalgam. He also would not do any work on mine unless it was vitally necessary (which I didn't appreciate at the time, but now do). So, I think he knew about the issue, but didn't say anything to me because he didn't want to frighten me or get into trouble or whatever.

It "may" be true that only a small amount leaks out from the fillings, but they have to look at many factors in determining whether amalgam is poisonous. For example:

1. Exposure at insertion. Amalgam doesn't set for 24 hours. There is thus a lot of exposure.

2. Continued exposure daily (in micro amount) from every amalgam placed

3. High exposure at removal.

Now add to that biological variances:

1. Some people have biological sensitivity to toxins

2. Some people have biological sensitivity to heavy metals

3. Some people are slow excreters of toxins

4. Some people are non-excreters of toxins

5. Some people are gentically predisposed to conditions that exposure to mercury can trigger

Then consider:

1. Mercury is second most toxic material on Earth to humans. Therefore, amalgan is innately toxic because it contains the second most toxic material on the planet. When a filling is removed from the mouth, it's disposed of as "Toxic Waste". If it is "toxic waste" when removed, it is "toxic" when it is in. They can't have it both ways.

2. No safe amount of exposure has ever been proven

So, in all, those who support amalgams, are failing to look at the bigger picture. They are failing to consider the intial exposure at insertion, the continued exposure for life of filling, the exposure at dental work, and the individual biological components of the person.

In other words, they are exposing their patients to the second most toxic material on the planet, and playing Russian Roulette in the sense that they have no way of knowing how this potent neuro-toxin will affect that person i.e. how well their body can excrete it, how well their body can resist it, how much will be accumulated in the body, and how long it will take to exhibit signs of toxicity.
