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.

Also in nature we only see ‘successful’ adults, cos any animal that – in this case – has not well aligned teeth, causes itself harm, inflammation, cannot feed properly and dies.
