I have had absolutely no interaction with this entity in my decades of dentistry.
None.
Note those molars hanging around her neck.
They did not come from a child, residing under a pillow.
She cannot overcome her deepest desire, the acquisition of teeth...
Noting that stringing deciduous teeth together in jewelry construction presents much more of a challenge than those permanent teeth...
...and their lengthy and sumptuous roots...
provides an excuse for grabbing those nice vital molars...
You're right, Martha. Root resorption by the erupting succedaneous tooth will render these little guys all the more ready for that tongue-wiggling that's sure to follow.
The second cousin to the Tooth Fairy has a penchant for those nice long roots...
As her good second cousin had already absconded with those precious little central incisors, the angered evil entity had to make her visit to this child worthwhile...
No wonder the Fairy community eschews her.
