Signs of Davis Square: I'm spitting mad

The "Dental" is fine, and the use of black rather than pearly white letters is droll. But that "Arts" bothers me. I don't really want a creative dentist, and certainly not one with an artistic temperament. ("You Crest-eating Philistine! I'm trying to make a statement about the futility of belief, and you just want to eat corn on the cob!") The smeary red lettering doesn't help matters. Does Peter Lorre work as a hygienist here?
