The last.fm page is similarly bare, saying only "Slow Teeth sounds like vaudevillian anarchofolk, a haunted cabaret." Archive.org says they're from Portland. That's all I got.
They're kind of like Blackbird Raum or Dandelion Junk Queens. The songs are really catchy and great which is always a nice surprise when you basically find something on the back shelf of the internet with two years worth of dust on it.
'Dead Sailors' and 'Oh, Penny' are in particular very good songs.
