This article is from the Dental Amalgam FAQ, by anonymous.
He is wrong - even the dental authorities now admit that
some mercury leaks.

World Health Organization Figures (World Health Organization,
Environmental Health Criteria 118: Inorganic Mercury, Geneva, 1991.)
The World Health Organization has calculated the average human
daily dose of mercury from various sources is:
Dental amalgam = 3.0-17.0 ug/day (Hg vapor)
Fish and Seafood = 2.3 ug/day (methylmercury)
Other food = 0.3 ug/day(inorganic Hg)
Air & Water = Negligible traces (NOTE ug = Micrograms)
From another source:- The US Environmental Protection safety
limits for mercury vapour are 10 ug per day, yet research
shows that fillings contribute between 1 and 29 ug/day - 3 times the
limit.
(Even those figures could be conservative for the possible upper
limit for mercury from amalgam - ie. if an old amalgam
filling is drilled carelessly, many HUNDREDTHS of a gram of mercury
could be released as vapour - W.H.O. figures were (ug) millionths of
a gram! Also, as I mentioned, what if the manually performed "mix" of
the amalgam, performed by a busy dentist, was incorrect - ie
60% Mercury, not 50%? All research is based on "perfect" mix
amalgam.. And also remember the new "copper" amalgams - all research
is based on traditional less leaky silver amalgams..)
There is an extract from a text on amalgam issued by the British Dental
Association via thier internet home page. While this
text has a strong "pro-amalgam" bias, it does have these
interesting quotes..
"Can mercury from amalgam fillings reach the rest of the body?
Like most bio-materials, dental amalgam is not inert. Amalgam
fillings release mercury vapour, especially when teeth are
chewed on or brushed. Some of the vapour is exhaled but some reaches
the rest of the body through inhalation. Some also dissolves in saliva
and is swallowed. The amount of mercury which reaches the rest of the
body is very small, though related to the number of teeth with amalgam
fillings. Much of the mercury entering the body is excreted but some
accumulates in certain organs - especially the kidneys but also in the
brain, lungs, liver and gastrointestinal tract."
" About 3% of the population are estimated to suffer from mercury
sensitivity. Reactions sometimes occur in the soft tissues of the
mouth next to fillings..."
Is "sensitivity" just a semaphore for "poisoned by"?
The rest of the document puts its case as best as
possible, selecting the most "pro-amalgam" research possible,
but the very careful wording used throughout is noticable
- very different from the bold assertions of safety they made
in the BBC Panorama program. (see WWW site below for complete text)
