Why Lotus Is Not A Dentist

So Lotus hasn't lost any teeth yet.  None of them are even loose.  This is a fact that she's growing increasingly distressed about as the days go on, and her four-days-older-cousin has lost not one, not two, but four teeth.
Last night, I was tucking the Big L. into bed, and we were talking about Kala's newest tooth loss.  Lotus made me test each of her teeth to see if they were maybe wiggly after all.  They weren't.

"Well, Mommy, you just have to stop keeping me away from sugar, that's all."  Lotus says.
"Why's that?" I say, looking at her teeth as I ask.  They really are getting too small for her head.
"Well, if you let me have all the sugar I want, in two days, I guarantee that they'll fall out." 
"Baby, they're supposed to fall out, not rot out."  I feel it's necessary to point out the obvious.
"At this point, Mama, I don't care."  she says in exasperation.  "This is getting embarassing."
