One of John Lennon’s teeth was sold at an auction for £19,500 last week.
Canadian dentist Michael Zuk, 49, bought the tooth over the phone when it went up for sale in Stockport on Saturday.
The discoloured tooth, which also has a cavity, was given by the Beatle to his housekeeper Dorothy Jarlett at the height of his fame in the mid to late 1960s.
Mr Zuk, who has written a book on celebrities’ teeth, said: ‘Once I heard it was up for sale I had to have it.’
He plans to display the tooth in his surgery as well as take it on a tour of other dental surgeries and dental schools.
The tooth was from a collection of rock memorabilia owned by Alan McGee, former boss of Oasis’s label Creation Records.
