If you have fillings in your teeth and you bite tin foil, it hurts why?

Question

Im not doing it as a habit. was just curios about whats happening when it is done.

Answer 1

Well sometimes i eat a Kit-kat and do it by accident and it hurts so much, I fall off my skateboard all the time and cutting my chin open and having 5 stitches really didn't hurt as much as when this happens to me. It is painful

Answer 2

its metal, course it's gonna hurt

Answer 3

it does hurt. your giving me chills thinking about it!!!

Answer 4

That is a myth.

I have fillings now, but when I didn't have fillings, it would hurt if I bit down on tin foil. The fillings have nothing to do with it.

I believe it's connected to the make-up of the tin foil and the nerves in your teeth.

Answer 5

dont bite on the tin foil!!!! its causing a galvanic reaction in ur mouth like battery. ask ur dentist to change ur silver fillings to composite or ceramic ones

Answer 6

Because you have the old style metal fillings.

The metal in the fillings causes a chemical reaction with the metal content of the silver paper.

Answer 7

DONT BITE TIN FOIL AND THEN IT WOULDNT HURT

Answer 8

go and see your dentist that dose not sound right

Answer 9

Tin foil is actually aluminium. Your fillings are silver amalgam. There are enough electrolytes in saliva that you create a small electric current. If you have any of the modern ceramic fillings, you won't get the same effect because the ceramic used is non-conductive.
