Why did I pick these books (10 of 10)?

If you search for "White Teeth" in Google Images, the Zadie Smith novel comes up first only at position 16. Why the book's title, I am wondering for the first time?
Suspicious about the commercial success of White Teeth, I postponed reading it, but became an instant convert by the author's On Beauty, which I had read because of E.M. Forster's Howards End.
