The slime of some slugs is mildly anaesthetic, to dissuade predators. If Animal Planet is to be believed, this fact led to the treatment of toothaches, waaaay back in the day, by sucking on a slug.
I’ve had very painful toothaches, in recent memory, and I would’ve done some fairly dramatic things to be rid of them, but even in extremity…no.
