Now magazine has published before and after pictures of a number of celebrities who have had work done on their teeth.
Number one on the list was the gorgeous Cheryl Cole who has been transformed from girl next door to national celebrity.
The Geordie songstress' star continues to rise, with a judging role on The X Factor helping to supplement a burgeoning solo singing career and the success of her band Girls Aloud.
While not ugly before, the soon-to-be divorced Mrs Cole looks more confident of her smile than she did in her pre-work days.
Other celebrities on the list include Top Gun and Mission Impossible star Tom Cruise and Twilight pinup Robert Pattinson, who both seem to have benefited from a trip to the dentist.
Despite his rock 'n' roll image, former Oasis star Noel Gallagher has also had work done, turning a gap-filled grin into a smile full of pearly whites.
Oasis split up last year, but Noel's brother Liam has now reunited with Gem Archer, Andy Bell and Chris Sharrock to form Beady Eye.
