[For as much as Henry avoided the answer for the sake of bad storytelling, he doesn't seem too reluctant to provide his reasons for holding onto teeth, much less any other excess. Henry keeps right on smiling and points a finger back.]

Oh, all right. Maybe it was just to see if you REALLY wanted to know, that's all. [It's no big secret; Henry keeps talking in his regular unchecked volume.]

You see, things like teeth work great as components casting a curse. That's why a set of teeth make me smile. I could use fingernails or locks of hair, true, but teeth are harder to come by, which obviously means they're more valuable and potent. [He waves a hand.] I don't make the rules, I just practice 'em. But teeth hardly compare to things like dragon scales, the blood of a fell beast, the tears of a pegasus... Oh, the things I could do with those!
