Fillings and tin foil.....AAARRRGGGHHH!?

Mostly right answers above: Teeth are primarily made of calcium (soft metal) and saliva is a wonderful conductor. When a dissimilar metal touches a silver or gold filling, it sets up a galvanic current (just like a battery) If your tooth is alive, it gets zinged

It's because you have 2 different metals with a liquid between them, this generates an electrical current in the same way that a lead acid battery in your car does. Your mouth is a lot more sensitive to electricity then your car, so OUCH!!!

Although that is the reason, I don't care too much, all I know is it hurts like mad

I think it has to do with a tiny electric field set up by the two metals touching.

Currents interior a filling do no longer could desire to hold approximately issues. purely whilst it leads ti currents interior your head (for those with greater advantageous than one cellular) it relatively is observed. the ideal evidence is user-friendly: chew on a bite of aluminium foil with a metallic dental filling. the two diverse metals will create a small voltage/present day, and the present flows for the period of the mouth/jaw and so on.

the body is full of magnetism.

these two metals form a current that goes thru the nerve to ya brain,signaling pain..........simply an electrical current,weak at best,enough to hurt

Sure I know what it feels like, I think it's an electrical charge. I get white fillings now. lololol xxx

galvonic effect

well i think it has somethin to do with ur bodys natural electrical current or something like that aided by ur salivia idk one of my teachers told me in elementary school...

horrible is`nt it, i get the same with chocolate
