Katie Holmes Katie Holmes We hope the Tooth Fairy has won the Lottery.

Because Katie Holmes may need a visit from her.

And with her oodles of cash, we doubt a pound would do.

But maybe the Tooth Fairy can just help us solve this gnasher mystery.

See, Katie's been snap-o-rama'd leaving her apartment in Manhattan.
