Human tooth sharpening

Many cultures have practised this form of body modification. In Bali, in a ritual known as Potong gigi or cut teeth, teenagers have their canine teeth filed down because it is thought they represented negative emotions such as anger and jealousy.{{cite news|work=Vice Asia|date=2018-10-30|title=Grinding Teeth: The Wild Indonesian Coming Of Age Ritual|url=https://www.youtube.com/watch?v=RwGNP13LWi8&feature=share |archive-url=https://ghostarchive.org/varchive/youtube/20211221/RwGNP13LWi8 |archive-date=2021-12-21 |url-status=live|accessdate=2019-02-13}}{{cbignore}} It is also seen as a way to spiritually separate them from their animalistic instincts and ancestors. After this tradition is completed the teens are now considered adults and are allowed to marry. During this ritual the person receiving the procedure is dressed in traditional clothing and would be carried from place to place by their parents as they are not allowed to touch the ground. This is done to avoid encountering evil forces. In a more modernized version of the ritual, the teen would wear socks to walk from place to place in order to stay off the ground.

Around the year 1910, the African Herero people participated in forms of tooth sharpening. Both the boys and girls at puberty would have four of their lower teeth knocked out using a sledgehammer. This was followed by the top teeth being sharpened to points that resembled a "V". The tribe regarded this tradition as a form of beauty. It was said that a girl that had not undergone this procedure would not be able to attract a lover.{{cite book|last=Frazer|first=James George|authorlink=James George Frazer|date=2006|title=Totemism and Exogamy: A Treatise on Certain Early Forms of Superstition and Society|volume=4|publisher=Kessinger Publishing|page=188|isbn=1-4254-9924-4}}

In ancient China, a group called Ta-ya Kih-lau (打牙仡佬, literally "仡佬 (Gelao people) who beat out their teeth") had every woman about to wed knock out two of her anterior teeth to "prevent damage to the husband's family."{{cite book|last=Frazer|first=James George|authorlink=James George Frazer|date=2006|title=Totemism and Exogamy: A Treatise on Certain Early Forms of Superstition and Society|volume=4|publisher=Kessinger Publishing|page=187|isbn=1-4254-9924-4}} Some cultures have distinctions between which sex does what to their teeth. In the central Congo region, the Upoto tribe has men file only teeth in the maxillary arch, whereas women file both maxillary and mandibular arches.{{cite book|last=Frazer|first=James George|authorlink=James George Frazer|date=2006|title=Totemism and Exogamy: A Treatise on Certain Early Forms of Superstition and Society|volume=4|publisher=Kessinger Publishing|page=193|isbn=1-4254-9924-4}}

The Mentawai people have also traditionally engaged in this practice.{{cite book|last=Ver Berkmoes|first=Ryan|year=2010|title=Indonesia|edition=eBook|publisher=Lonely Planet Publications|page=428|isbn=978-1-74104-830-8}}. The Mentawai people believed that the soul and body were separate. If the soul was not pleased by its body it would leave and the person would die. As a result, the Mentawai people started modifying their bodies to be more beautiful. In Mentawai culture, those with teeth that have been sharpened are deemed more beautiful. Tooth sharpening would have been traditionally done at puberty, though contact with outside civilizations has resulted in a decline of tooth sharpening.{{cite web|title=Teeth Chiseling|website=National Geographic|date=14 March 2008|via=YouTube|url=https://www.youtube.com/watch?v=314KpEm88LU |archive-url=https://ghostarchive.org/varchive/youtube/20211221/314KpEm88LU |archive-date=2021-12-21 |url-status=live}}{{cbignore}} Today, the Mentawai people use a sharpened chisel and another object that acts as a hammer.
