Can't believe no-one else has made a comment about how great the form id "230" (tooth-hurty) is, yet. Bravo.
One of the minor villains in my D&D campaign is a literal living nightmare - one of three. Each one is named after a time of night when they appear, and this one is named 2:30 - because he really likes the nightmare where your teeth all fall out.
He's the spookiest one of them all, but the least dangerous.
