they can replace them constantly, unlike mammals where we get a set amount of teeth.

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

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

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 mightis less of an issue for them.

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

they probably shed it often where it doesnt become a large problem with like mammals. also animals that tend to eat carriorn or dead animals have unique adaptations around bacterial infections.
