I Have heard that Electromagnetic fields such as from Mobile Phones and Computer Monitors Increase significantly the ammount of vapour released from mercury fillings. I have only got about six fillings but for the last ten years or so I have been sat at computer screens for hours on end most days.
It's been over that period that I have had symptoms of mercury poisoning. My mum has got about twelve fillings and seems to be perfectly healthy at the mo. The difference is that she spends most of the day doing house work and is not sat looking at the computer screen. But when she does use the computer for long periods she starts getting headaches.

could this be one of the reason's why some people suffer and other's don't.

Here's a link.

I think the reasons why some may suffer and not others is quite complex. I have been sensitive to EMF's for over year now and had my fillings replaced about 6 months ago. I still experience discomfort from EMF's though not quite as bad. I thinks that EMF's, depending on there strength, have a deleterious effect on the body anyway regardless of whether we have mercury amalgam fillings in or not. It does appear that EMF's can accelerate the release of mercury vapour from fillings as you pointed out. It has been suggested that other factors such as poor immune sysytem also have a part to play in why some suffer and not others. And mercury is immunotoxic.

Here's an interesting observation...

I noticed that the taste of metal in my mouth was much stronger after I talked on my cell phone.

It's also interesting to consider that fillings with higher voltages on their surface emit much higher quantities of vapor (according to Huggins research). There is, of course, an intimate relationship between voltage and magnetic fields (one never exists without the other).

Also consider that magnetic fields induce voltage in conductive metals. So perhaps there is a positive feedback mechanism here.

I wonder also if the electrical currents that fillings generate could effect the muscle's in your jaw. My jaw muscle's seem to be tight all of the time, ( a symptom of tmj). As electrical current is known to make muscle's contract. Maybe alot of people who clench there teeth at night are doing it involuntary because of electrical current in there fillings.

Absolutely!

I used to grind my teeth at night?Nearly every night for years?and had a very tight jaw. I ground my teeth so hard I was actually afraid they would break. After the removal, this went away immediately. Now I grind once a month at most, and this is only after eating fish or doing something else I shouldn't do (I do cheat occasionally).
