The 24-year-old singer was inspired to create the unusual piece of jewellery after one fan posted her one of their pearly whites.
Taking to Twitter, she wrote, 'I've received 1 tooth from a fan. I made it into a necklace. But now I really wanna make a fan tooth necklace to wear to an awards show.
'So. What I'm getting at is please send me your teeth. I'm dead serious. I need your teeth. (sic)
'Wisdom teeth?? Cmon. Yall got some of those laying around. Ok so send them to my the following address:: ke$ha po box 120479 / nashville tn 37212
'I love my fans btw. Let me wear ur teeth.'
The kooky Tik Tok singer has previously admitted that her mother turned her placenta into a necklace for her which she wears to channel her psychic side.
'My favourite keepsake is my placenta,' she said. 'My mum found in my basement, crushed it up, and made into a necklace that I wear every day to improve my psychic abilities.'
