Impact unknown! Meanwhile many American dentists install mercury amalgam (about 50% Hg) in tooth cavities inches from the brain where it will sit for years on end. How can anyone support this with a straight face. The response is something like 'yes,we know mercury is a devastating neurotoxin but it's tightly bound in the amalgam and there is no proven statistical relationship to say it's dangerous'.

Haven't amalgam fillings been phased out yet? At least in the Netherlands most dentists now use composites to fill cavities.
Wikipedia seems to suggest that the performance of those is comparable to amalgam: https://en.wikipedia.org/wiki/Dental_composite
Cost also seems to be comparable, where composites may even be cheaper than amalgam, because of all the environmental issues surrounding the amalgam material.
In Poland you only get composite if you pay extra, National Health Fund (mandatory insurance) gives you the amalgam. And a month of waiting, where time is crucial. And no anastheatics for drilling. SLAVIC FUN!
Yeah, I believe it's the same in the UK. I don't think the month of waiting is too bad, cavities take a long time to develop. A checkup every 6 months should be enough to prevent them from developing too far.
In my experience NHS dentists in the UK will give you composites if the filling is in a visible area. Also, they do provide anaesthetic!
I think it depends on the dentist. Mine uses amalgam--of which I already have lots (unfloridated water growing up, among other things probably). On the other hand, a friend of mine told me recently that her dentist wouldn't use an amalgam filling in spite of admitting that the composite wouldn't last as long. This is in US.

I pay for private treatment in the UK and recently had a new amalgam in a non-viewable area because I was told it was far better for the situation and would last longer. Otherwise I always have composites.
When I was a teenager, I accidentally swallowed a damaged mercury filling. Luckily I still seem to be alright :-)
