I have a great dentist. He says he regularly sees patients who have cracked teeth eating crusty French bread and the like, so, eating crust could mean a trip to the dentist. I never much liked the crusts of white bread. I ate a lot of that when I was growing up. The whole Wonder Bread years thing was big in my generation: pb&j or baloney, who knew what kinds of vile stuff got put in bread. But the crusts were never anything but ugly dry and bitter spongy brown stuff. Now that I live near a good french bakery, I'm happy to eat the crusts, but that was then and now is now.
