After reading the article posted by ode, I searched gold, amalgam, and
"galvanic corrosion" (as suggested by the author) and came up with this...
====================================================================================================
Clinical management of galvanic current between gold and amalgam.
Williamson R.
Department of Oral Health Practice, University of Kentucky College of
Dentistry, Lexington, USA.
Placing a strip of rubber dam or similar insulator between the contacting
dissimilar restorations is a diagnostic technique for relieving and
evaluating painful galvanic currents. Treatment modalities vary according to
severity of pain. In cases of little or no pain, nothing is done, and
corrosion products are allowed to form an insulating cover over the
offending restoration. For patients with severe pain that does not improve,
treatment may consist of placing a composite restoration in the amalgam
restoration to break the interproximal dissimilar-metal contact. For painful
currents caused by occluding restorations, a coating of unfilled light-cured
resin over the offending amalgam breaks the metal contact and allows
corrosion product buildup. Galvanic currents can occur and cause pain, but
this is generally shortlived and should not influence the dentist's choice
of an appropriate restorative material.
====================================================================================================
This makes me FURIOUS. Can't these people understand that if there is a
galvanic current that SOMETHING is giving up electrons and don't they KNOW
that it is the mercury?
But no, let's make removing the amalgam the last option.
Sorry, it's a hot topic with me.
But at least now I have plenty to copy and take to my dentist to show him
that the pain I've been in is not just in my "head" (although it is in my
head :-)

Subject: CS>gold crowns and battery effect
This topic is of great importance to me as I came down with severe chronic
fatigue within weeks of having two gold crowns placed in my mouth along
with a host of pre-existing mercury fillings. I have also experienced
SEVERE electrical shocks in my neck and back of my skull on occassion.
This only started after the gold crowns were placed and I know that this
is due to a battery effect (but of course my dentist does not believe
this).
These shocks happen about 6-10 times an hour and when one hits I am in a
great deal of pain. They last for probably a fraction of a second but
they really, really hurt. This will go on for 24-48 hours, even through
the night, then go away. These episodes come on about once a month.
I went all summer and most of this fall without an episode but had another
one a couple of days ago.
One of those gold crowned teeth had to be pulled. If I have another
electrical shock episode I think I'll just go to my dentist and DEMAND
that he pull the other one.
I want to go to Mexico to have the rest of my amalgams and root canal
teeth removed but as a stay at home mother we have very limited funds and
even with the huge discount, a trip to Mexico would cost us money we don't
have right now.
Anyway, I see that I'm rambling.
I remain very interested in this topic!
Blessings,
Lea Ann

You are talking about a battery effect?
I you have a gold crown, mercury 'can', but not always, slowly plate to
that crown.
Pretty detailed article here on gold / amalgam reactions..a bit over my
head
http://www.ibiblio.org/amalgam/
The electrochemical potentials in the order from most reactive (+) to
least reactive (-):
Zn & Zn(Hg) > Sn > Cu(Hg) > Cu > Ag > Hg > Au
+.7626 +.1406 -.3511 -.3400 -.799 -.852 -1.42
Reverse amalgam-ation, perhaps, where silver sucks mercury that's alloyed
with silver out of fillings?
I dunno, mercury has a pretty strong tendency to dissolve things like
silver, zinc, tin, gold and lead into it at room temperatures.
Never tried it with aluminum or copper. Maybe those too.
