Ask Ariel: Would stepping on a werewolf tooth and having it break skin be enough for the curse to take root? It was fresh, still coated in saliva, if that matters.
...Also do werewolves normally lose teeth during a Full Moon Rampage, or should I be concerned about something living here being strong enough to knock teeth out of a werewolf's mouth?
Ariel: "I'm not quite sure, to be honest. Can't say its ever been tried, or at least not documented. Assuming you don't want to risk dedicating yourself to science and becoming a Werewolf yourself, I'd suggest seeking treatment as a precaution."
Ariel: "As for the teeth... They don't normally lose teeth so it had to be caused by something. Though I wouldn't worry too much. It certainly takes a lot of force to hit something, be it Human or Werewolf, so hard that it knocks a tooth out. But the range of beings with enough strength to do it are plenty. Sure it could be an eldritch horror, but it also could've been a Human with a solid kick in the right angle."
Ariel: "And that's only for a healthy tooth! The chances of a Werewolf with the silent menace of gingivitis is entirely on the table!"
