The John Lennon tooth that a Canadian dentist bought at auction last year is going on display in Edmonton. Kirsten Zuk, the sister of Dr. Michael Zuk, has used former Beatle's molar in a sculpture of Lennon that is being displayed through August 26 at Edmonton's Fringe Festival. Kirsten Zuk plans to solicit donations from viewers for Smile Train, an organization that helps financially strapped children receive corrective surgery for cleft issues. Michael Zuk was the high bidder for the tooth, which had been owned by his onetime housekeeper Dot Jarlett, paying more than $32,000 at a November auction in England. Zuk has also published a new book, "Confessions of a Former Cosmetic Dentist."
