Slain Beatles star John Lennon's tooth is to tour dental practices all over Britain as part of an oral cancer awareness campaign.

Dentist Michael Zuk paid $30,000 (Gbp19,000) for the tooth at auction and part of the gnasher has been turned into a necklace pendant by jewellery designer Ari Soffer.

Now the John Lennon DNA Tooth Necklace will hit 16 dental practices over the coming weeks to highlight Britain's National Mouth Cancer Month.

Visitors to the dentists who will have the tooth necklace on loan will get the chance to pose for pictures with the odd accessory.
