What's the difference? And when should I use don't and dont?

The only correct form of this is don't. You should always use the apostrophe. Dont is incorrect.

One point more

dont has no meaning in English apart from DONT which is the name of a bridge (card game) opening convention

And when should I use

don't when appropriate to short do not

and

dont as DONT or D.O.N.T. when you play the bridge

Emotion: smile
I see, I imagine the same thing goes for wont, cant, and shouldnt? won't, can't, shouldn't?

Thanks for the reply.
Yes. You must always include the apostrophe.
Students: Are you brave enough to let our tutors analyse your pronunciation?

I think we need to accept that "don't" has no been contracted to "dont", that the way new works are formed

Does not => don't => dont

I have started adding it to all my spelling dictionaries

That is an unusually stupid thing for a learner to do.
