But why? don't they have many sets of teeth when growing up?

they can replace them constantly, unlike mammals where we get a set amount of teeth. because thier bite forces, or ripping causes them to lose teeth quite often.

I imagine, they can still get inflamed gums or similar, if something gets stuck in there...

they probably have a powerful immune system to deal with decaying matter, or carrion. also because they constantly replace thier teeth, caries and gum disease is less of an issue for them, as they wont get tartar or bacteria getting trapped in thier teeth.

Doesn't mean it's nice to have gum infections though. I can also imagine they are more of a threat to baby crocodiles.

Exactly and crocodiles keep growing teeth so they actually did evolve a defense against the dentist…
