Catherine Zeta Jones Our fave celebs are sat in the waiting room of the showbiz dentist surgery.

We're asking them to open wide and show us what they've got.

They thought they could fool us into thinking they were born with A-list grins, well they can think again...

... Because we have the shocking pics to prove otherwise.

Now we don't have their dental records before us - but some things speak louder than words.

And we reckon that these pics do just that.

So have a nosey around the chops of our stars and examine their cheeses of old and new.

You may be v interested by what you find because we couldn't bloomin' well believe our eyes.

The perfect set of pearlies we're used to seeing weren't actually what nature gave them... oh no.

It seems that many of our starry pals have been given a helping hand.

So sit back, relax we promise this won't hurt and have a mooch through our gallery at the transformations made on these celeb teeth in our gallery below.
