English: Knocking out a girl's tooth — Kaitish tribe.
In many Australian tribes it is the custom to knock out one of the upper incisor teeth as soon as a boy or girl reaches a certain age.

English: Old Kaitish woman knocking tooth out of young girl to make her more attractive.
All the girl's teeth were sound, but the men of the tribe had lost interest in teeth extraction as a magic mystery, and instead of making it a male privilege, as tongue-piercing still was, let women, and even girls, have their teeth knocked out. And they were keen on it. The tooth , having been loosened by pressure with a stick, is being knocked out with three sharp blows. Afterwards, the girl danced with pleasure.
