When is there a dipole moment?

Are you just looking at electronegativity differences? Then is there a cutoff?

There are always induced dipole induced dipole intermolecular forces between all molecules and these are temporary dipoles. Dipole dipole moments and other dipoles occur when molecules are polar, so they are permanent.

At what point do we consider two atoms to be polar?

Dipole moments result from differences in electronegativity as more electronegative atoms pull the electrons of less electronegative atoms closer to them. This same effect also makes a molecule polar as electrons are being shared unequally.
