The Tooth Fairy puts her hand deeper into her pocket depending on where she happens to be, according to a new poll which revealed that some children receive £5.05 more than their peers.
London seems to be the Tooth Fairy's favourite city as each child receives an average of £5.10, while children in Hull wake up to an average of just 5p after losing a tooth.
The poll, which was conducted by www.MyVoucherCodes.co.uk, involved a total of 2,091 parents from around the UK, each with children aged between four and 12.
The luckiest children are those living in London, followed by Cambridge (£5.00), Cardiff (£4.75), Liverpool (£4.50) and Manchester (£4.35).
The poll found that the Tooth Fairy is least generous when she visits Hull, followed by Portsmouth (10p), York (10p), Glasgow (11p) and Nottingham (11p).
Mark Pearson, chairman of MyVoucherCodes.co.uk, said: "It was a surprise to see some children get as much as £5 per tooth.
"That works out to be around £100 by the time they've lost all their milk teeth!"
