Gold teeth were first present in America during the Jim Crow era. Originally, it had become a tradition in Louisiana before becoming a fashion trend around the Deep South region in the early 1900s.
After slavery, it was believed that many African Americans who were former slaves began getting the permanent gold caps to replace their rotting teeth that have deteriorated. It later became a symbol of wealth for ex-slaves who once worked on the plantation fields in the South, specifically Louisiana, where it first become a tradition.
Blues, Jazz and freed slaves who had money would get the permanent gold cap fillings as a fashion statement as flaunted by Jack Johnson, the first African heavyweight boxing champion.
