Post by Shoe-Chucker 2Does you dentist still push mercury fillings.
And do they properly dispose of it?
ask them.
dentists were never told the dangers of Hg. well, not till recently.
Mercury is a nerve poison, and the ADA doesn't want you to know.
Because they have lied for years.

When My Mercury-Amalgam Fillings Were Removed, 17 Physical Symptoms
Went Away and Numerous Emotions Issues, Including Depression.
After a friend told me how she cured her 5-year bout with doctor-
diagnosed Fibromyalgia by having some of her mercury-amalgam
("silver") dental fillings removed, I began researching the subject.
Remember, you can be exposed to mercury through "silver" dental
fillings, tattoos, coal-burning power plants, vaccines (yes, many
vaccines still have mercury in them as confirmed via independent
testing), dentures (per Huggins), and certain medications.
I really want to the world to know and understand that mercury can
cause depression, OCD, Autism, and numerous other emotional/
psychological problems in humans.
Please see this blog in this website for more information.

The fact that mercury can be absorbed and reach toxic levels in
human tissues makes any and all exposure to that element of scientific
interest.
(reach toxic levels, could this come from amalgams? It says makes
*any*
and*all*)
Studies showing measurable elemental mercury vapor release from
dental amalgams have raised renewed concern about amalgam safety.
Mercury vapor absorption occurs through the lungs, with about 80% of
the
inhaled vapor being absorbed by the lungs and rapidly entering the
bloodstream.
(Where does these mercury vapor come from??)
Following distribution by blood circulation, mercury can enter and
remain in
certain tissues for longer periods of time, since the half-life of
excretion is
prolonged. Two of the primaryt arget organs of concern are the central
- quote -
When amalgam fillings, which normally contain 50% Hg, are made with a
tracer of
radioactive 203Hg and then placed into monkey teeth, the isotope
appears in
high concentration in various organs and tissues within 4wk.
Research in molecular biology has elucidated mechanisms that may
underlie the
toxic effects of mercury.
The thyroid has been identified as the target organ for the toxic
effect of
mercury in occupational exposure to mercury vapour in low doses.
Clinical studies of the effects of mercury on occupationally exposed
workers,
using modern diagnostic methods, have elucidated the connection
between
dose
and effect. They have also identified and quantified
neuropsychological
symptoms at low exposure levels..
Low-level chronic exposures to mercury may affect the peripheral
nervous system
resulting in polyneuropathies (reduced sensory and motor nerve
function) and
neuropsychological effects (visual alterations, sensory loss, stress)
(ATSDR
1989); these effects correlate to tissue levels of 20 to 40 µg/g.
Neuropsychological effects were also reported by Smith et al. (1970)
for
occupational exposure to mercury levels of > 0.1 mg/m3. Mercury
concentrations
below this value did not appear to cause observable effects. Kishi et
al.
(1993) reported that neurobehavioral and motor function effects
persisted in
ex-mercury miners more than 10 years after cessation of exposure.
Once inhaled, elemental mercury is mostly converted to an inorganic
divalent or
mercuric form by catalase in the red blood cells. This inorganic form
has
similar properties to organic mercury. Small amounts of non-oxidized
elemental
mercury continue to persist and account for CNS toxicity.
Elemental mercury, as a vapor, which escapes from fillings, penetrates
the
blood-brain-barrier and enters the CNS, where it's ionized and
trapped,
attributing to its significant toxic effects

Environmental Effect of Dental Amalgam
Mercury is one of the most toxic substances commonly encountered, and
according
to Government agencies causes adverse health effects in large numbers
of people
in the U.S.[1] The extreme toxicity of mercury can be seen from
documented
effects on wildlife by very low levels of mercury exposure. The
average amalgam
filling has more than œ gram of mercury, and has been documented to
continuously leak mercury into the body of those with amalgam fillings
due to
the low mercury vapor pressure and galvanic current induced by mixed
metals in the mouth.

Low Level Mercury Causes Behavior Problems During Pregnancy
Subtle behavior problems were observed in mice offspring exposed to a
single low level mercury dose.
In summarizing the results of their study, the researchers stated,
"This hypothesis generating study showed highly significant
correlations
between mood scores and most measures of low level Hg (mercury)
exposure. The
specific mood measures most associated with Hg exposure were tension,
fatigue,
and confusion. The strength of these associations suggests that mood
should be
included for investigation in future hypothesis-testing studies.....
Among the
cognitive and motor function tests, only the digit span and simple
reaction
time (nondominant hand) scores were associated with any measure of
exposure...... Overall, and despite the small size of the study
population,
this investigation found some evidence of adverse preclinical effects
at
mercury doses averaging 36 ugs/l in urine. The mood and symptom
results
of this
study agree with prior evaluations of both high and low urinary
mercury
doses.
These preliminary survey findings support a critical evaluation of the
adequacy
of the 50 ug/g creatinine biologic threshold for mercury proposed by
the World
Health Organization This is the first U.S. dental study to detect
potential
behavioral deficits at such a low level of exposure. A larger and more
comprehensive study is required to accurately determine a biologic
threshold of
adverse central and peripheral nervous system effects for elemental
mercury."

Dopamine Uptake in Brain Cells Changed By Methylmercury
Attention Deficit Disorder children were reported in other headings in
this
book as having altered dopamine levels. Several compounds, including
alcohol,
have been shown to alter dopamine levels in test animals. Now,
researchers at
Duke University Medical School have shown that even very low levels of
methylmercury result in dopamine and norepinephrine brain
neurotransmitter
changes.

Mercury exposure from mercury dental fillings, also known as "silver"
fillings and "amalgams", is a life long threat. When a person chews,
drinks, swallows and breathes, mercury released from dental fillings
is absorbed by the lungs and the linings of the digestive system into
the bloodstream. As they corrode, mercury fillings release ionized
mercury into the saliva, tooth pulp, and gum tissues leading to the
digestive system and bloodstream.
Measurements of momentary mercury levels in breath have been
scientifically collected in multiple studies. There has been much
debate about the potential safety hazard because mercury vapor levels
measured in the mouth are not always above the standards set for
exposure in the workplace.
Overlooked has been the amount of mercury in feces, which demonstrates
both exposure and excretion from the blood and tissues by the liver.
The levels measured by Osterblad et. al. in the article "Antimicrobial
and mercury resistance in aerobic gram-negative bacilli in fecal flora
among persons with and without dental amalgam fillings" published in
Antimicrobial Agents & Chemotherapy, 39(11):2499-502 1995 Nov; are
disturbing, and clearly demonstrate that human mercury exposure is
dominated by the presence of mercury dental fillings.
Osterblad found that on average people with mercury dental fillings
had 17 times more mercury in their feces than did people who had never
had mercury dental fillings, and had 11 times more mercury in feces
than did people who had all of their mercury dental fillings removed.
The group with mercury dental fillings had more than 1 part per
million mercury in their feces.
At the first standard deviation, the difference between these
populations becomes more dramatic. People with mercury dental fillings
had nearly 4 parts per million mercury in feces, 39 times more mercury
than did people who never had the fillings.
Osterblad's data indicates that 1 person in 1000 with mercury dental
fillings will have 10 parts per million mercury in their daily feces,
170 times more mercury than the average person who has never had such
a filling.
The safe limit of mercury allowed by the EPA in drinking water is 2
parts per billion (see ASTDR ToxFAQ CAS# 7439-97-6) . What Osterblad
found in the feces of people with mercury dental fillings was an
average concentration 500 times higher than would be allowed in
minimally safe drinking water.
The graph below compares the amount of mercury found in feces by
Osterblad et. al.. The group represented by the yellow bar had never
had mercury dental fillings. The group represented by the red bar once
had mercury dental fillings, but had them removed before the study.
The blue bar represents the population that still had mercury dental
fillings in their teeth at the time of the study.
