Celebrity teeth before and after! Cheryl Cole, Tulisa Contostavlos and Victoria Beckham’s old smiles

Brace yourselves (for more terrible tooth-related gags) AND for these SHOCKING sets of celebrity gnashers!

Cheryl Cole, Tulisa Contostavlos, Tom Cruise, Demi Moore, David Beckham and co. were not born with Hollywood smiles.

Fact.

Nor were they born with rows and rows of gleaming Daz white gnashers in their mouths.

And not just because no one – not even a super celebrity like Kristen Stewart - is born with perfect teeth in their mouths… or teeth anywhere else on their being for that matter. We think.

Yes even David-perfect-man-specimen-Beckham has had work done in the food and air hole that he (and we) like to call his mouth. Mmm David Beckham's mouth.

And he’s not the only one either! Take a look at the shock sets of celebrity teeth below – and see which stars have put their actual money where their mouths are (guffaw).
