Hyphenation in danish LaTeX

I can’t really make a minimal working example who shows the problem, because the problem just are there sometimes. But here is the code used:

documentclass[twocolumn, a4, 12pt]{article}
usepackage[utf8]{inputenc}
usepackage[danish]{babel}

begin{document}
end{document}

Sometimes the hyphenation splits the word incorrectly in the danish version. Like “marmo-rgade” or “kal-ksten”. That is one problem. The other problem is that it sometimes don’t split the word at all, so the word sometimes reaches into another column (and lay over another word).

I thought danish babel should solve this problem? Am I the only one with this problem and do anyone know how to solve it? I’ve solved it earlier by chaging the sentence – but always to do that in a long document is too hard.

Thank you very much in advance. Kind regards!
