American v British teeth
Ricky Gervais is the first to admit that his teeth are neither white nor straight - and Americans mistakenly think he wears bad false teeth for comedic purposes. Why the dental divide?
British teeth are not like American teeth.
Hollywood smiles are pearly white paragons of straightness. British teeth might be described as having character.
So much character, in fact, that Ricky Gervais says one US journalist complimented him on being prepared to wear unflattering false teeth for his role as an English dentist in his latest film, Ghost Town. Only he didn't.
"He was horrified that I could have such horrible real teeth. It's like the biggest difference between the Brits and the Americans, they are obsessed with perfect teeth," says Gervais.
Unlike many British stars hoping to make it big across the Atlantic, Gervais hasn't bought himself a Hollywood Smile.
But what is it about the bright white and perfectly straight teeth of Los Angeles that Americans love - and expect of their public figures?
