Question

Why does it cause pain to chew on aluminum foil?

Answer 1

You are making a small battery and experiencing "galvanic shock" due to a reaction between your saliva, your fillings and the aluminum foil.. . Search "electromotive series" for thousands of references.

Answer 2

TIN FOIL (AKA ALUMINUM FOIL) HAS ANY SHARP EDGES WHEN CRUMPLED UP. MANY TIMES THESE SMALL EDGES DIG INTO THE CHEEK AND GUMS.

Answer 3

Jeepers....have you tried chewing on fire ?

Answer 4

Dr. Sam is correct. You are creating Galvanic Shock. This is the interaction between the metals and saliva which causes an electric current to occur.

Answer 5

When you rip off a piece of aluminum foil the blade makes pointy, well, points on the edges of the foil. those points dig into your gums, puncturing them.. Ok, i may or may not have made that up, but it sounds good.

Answer 6

Tinfoil is made of aluminum and aluminum is toxic to the body. I see patients all the time who have too much aluminum in their body and they experience short-term memory loss, worse if it's compounded with other heavy metal toxicity.

Answer 7

I dunno? but once you experience it you will never do it again!!!trust me on this one!!!!

Answer 8

cause your body has electric pulses running through it and the foil acts as a conductor and connects pulses that shouldnt be connecting

Answer 9

If you have fillings, they counter act with the tinfoil and makes a sting type feeling. Although,you might not want to chew on tinfoil, its not the healthiest!
