I've been reading Les Miserables (which, sorry, I can't stop talking about until I stop reading it, which is due to be approximately never). One of the excellent things about it is the real focus on teeth—you hear about everyone's teeth when you get their character described. Poor Fantine has those pearly "cutters," the old grandfather has every one of his teeth! Then there's some other guy who has "not a tooth in his head." Clearly, there were a lot fewer teeth back then.
And it made me think of the kids books with teeth. There's Dr. DeSoto. There's Little Red Riding Hood. What else? It's funny, I read Fanny, which is a novel about Trollope's mother, and one of the historical details had her running over to the mantel whenever company came over to stick her false teeth into wax in her mouth.
It also made me think: the dentist (and orthodontist) are such a standard horror for kids, you would think they would feature more in books. I wonder why they don't? There's Freaky Friday (so good!) where her mother gets her braces off, but it's small. Help, where are all the teeth-related books?
