What prevents animals with sharp pointy teeth (sharks, alligators, etc.) from constantly biting their gums?

Question

With humans our teeth are designed and aligned pretty orderly so we can’t do this…but when I look at something like an Angler fish..I wonder how it isn’t constantly sinking those sharp ass teeth into itself every time it takes a bite.

Well generally animals with sharp teeth like that have the aligned like a zipper. Alternating and interlocking but fish like an angler fish have teeth that get so big they can actually properly close their mouths because their teeth stick out so to keep their food from coming out they lock their teeth together. But never are they just stabbing their gums every time the close their mouths and bite and stuff.
