It is believed that grils can be a symbol of power and social status. Wealthy Etruscan women in 800 BC removed their teeth, and then, by fastening them together with gold wire, they placed them back in their mouths. This was a way to show social status (Etruscan women had almost equal rights with men) and for aesthetic reasons.
During the classical period (from 300 to 900 AD), Mayan kings and queens drilled holes about three millimeters in diameter in their upper teeth and inserted round pieces of jade.
Only wealthy people and members of the royal family could afford this.
According to ancient Philippine myths, the deity Melu had golden teeth, so in the Middle Ages, Filipinos in Europe filed their teeth and decorated them with gold.
