Ok so my back tooth needs a filling,
on the side of it, it has a black line.
I'm not sure if its a crack,
I was thinking that if when the doctor drills the tooth will all crack and crumble? :S
My dentist is swedish and hard to understand nor does he understand me very well :/

I can understand why you're worried. Call attention to it before he drills and try to explain your problem. After he sees it, he will make the informed decision whether or not to drill.
Don't worry about it :)

I understand why you're worried, but your dentist went to school for this for a very long time and he most likely knows what he's doing. I hope it works out well, try not to worry too much.
