A crouton is a piece of sautéEd or rebaked bread

What kind of weak ass teeth do they have??

It's probably the same type of persons who think sparkling water "hurts".

Well.. I mean... she did turn out to be a wicked witch, sparkling or not.

Croutons don't hurt the teeth they hurt the gums an mouth, same as a sharp chip or cracker. Its like eating dry cereal as a snack. Its delicious but with an after taste of mouth ouch. Still worth it though everytime.
