A plant whose roots resemble human teeth.

I have had reasonably perfect teeth since forever. I can not say that any more in polite company. Resentment brews, jealousy, anger among those who are laid up in the dentist’s chair twice a month, sharp objects digging into parts of the human body most owners never see or contemplate as having an appearance. No more bragging for me. I learned my lesson. Bragging about perfect teeth is, to some, like bragging about one’s enormous genitalia. Or salary. The value of these assets (salary and genitalia) is illusory, but perfect teeth are forever.
