Thank you for all the replies George and everyone,

This sounds like a galvanic current (2 different kinds of metals in a
solution like your saliva can act like a battery, causing an electrical
discharge that gives you this "shock"). It's a relatively rare
phenomenon that unfortunately can't be avoided or predicted. Mostly
happens when an alloy filling is placed right next to a tooth with a
gold or other metal crown.
Good news is that it won't last forever; once the surface of the
filling oxidises it will become inert. I've heard some dentists used
silver nitrate to speed up this process, but I haven't ever used it.
The pain you felt while the filling was done was probably because you
weren't numb enough. It may have felt numb, but sometimes it's not
REALLY numb.

Regards,
George

I had two filling's one july 20th and one on aug1st, when I am eating
with a fork and the fork hit's them on the filling it hurts a lot, I am
confused about this and do not know if I should go back to the same
dentist, when he was drilling one of them it hurt like he hit a nerve or
something, I was thinking the teeth might have been good and did not
need a filling maybe thats why it hurt, any help on this would be
greatly appreciated
