Gold has been featuring in an unexpected place with latest trend seeing the precious metal being placed on teeth. Tooth jewelry is now the popular accessory in the US and the latest craze in the body art movement. Dr. Bruce Freund is a New Jersey cosmetic dentist who has seen an increasing number of hip-hop stars and young people in his practice who request a smile with some extra ‘sparkle.’ As Dr. Freund says, "Every body part has been painted, pierced or tattooed... why not teeth?" However the latest fashion is not a new idea, with anthropologist Michael Coe revealing ancient Mayans used to ground their teeth down and place a jewel where the piece of tooth once existed. The idea is very popular in Canada and Europe too, with rap stars cited as a key reason behind the trend, showing off smiles set off with gold caps.
