Still with his thumbs up even though he looks like he's been in a pub brawl
Now perfectly veneered
Aww, cute! But obviously Em didn't think so...
Just like her auntie (Julia Roberts), Emma's now not shy of flaunting her Hollywood whites
How has Becks naturally got this amazing set of gnashers? Jealous!
Looking beaut with her new smile. Although we personally think she was beaut before (minus the bangs and weird make-up)
This is proof that Jess hasn't actually aged at all
Is it just us or do we spy a swhiter shade of er, white?
Leaning towards the front (and leaning towards veneers)
Still keeping a fairly natural shape, we reckon these are a surefire improvement
The singer's pearly whites weren't always so pearly white...
But now she's looking a bit of all white
Just how young and natural does Katie look here?
As difficult as it is not to be distracted by this photo, Katie's glowing gnashers are so bright our eyes hurt
CZJ looks fresh as a Darling Bud Of May in her youth
Then her teeth got transformed into a smile that won Michael Douglas over
Once upon a time, Gord wore a magician's cast-offs and also had slightly yellow teeth
But then he got rid of the fuchsia shirt, went to the dentist and lived happily ever after
Uh-oh, Ro. Maybe you should've kept your mouth shut...
Life has been one hell of a dentistry rollercoaster, but at least Ronan's come out the other end
He might've been a Pop Idol back in the day, but he's not always been a tooth idol
Anyone else somewhat reminded of Ross from Friends in the glow-in-the-dark teeth episode?
Gnashers....everybody needs good gnashers....
Nothing short of a perfect smile for our Kyles
And Kylie's not the only Minogue to have a bit of polishing by the looks of it. Take a lot at Dannii's child star days which came complete with off-white gnashers
Now Dan looks like she's stepped out of a Colgate advert
Little Hermione once had a few wonky pegs
But now they have miraculously disappeared. Something to do with a spell perhaps?
A few gaps to speak of
Now there's not a gap to be seen
Super white, but 50 Cent obviously wanted to MIND THE GAP (sorry)
Now the rapper's got that Hollywood smile down to a tee
A few wonky front teeth obviously put Mr Clooney on edge
Oh George. We always thought you were perfect anyway
We can't see anything wrong with it, but Rylan was not a fan of his smile clearly
Words fail us regarding these pegs. Words also failed Rylan too as he could barely get his words out on BBBOTS
Pip was once not Dancing On Ice-Whites
But now he is! And straight along the edges too
Amazing hair volume but not such amazing teeth unfortunately
Now it appears the actor has definitely had at least a bit of whitening
Just like Chezza, Cher's not always had teeth to drill (sorry) for
The X Factor singer has now got a brand new set of pearly whites which she treated herself to earlier this year
Slash then, and now. Still would though, right? No?
PS - She's also either really, really small or that's one helluva bottle of bubbly.
Random question: Is it true that people with gaps between their front teeth are better singers? Zac? Anyone? No?
As if that's not exciting enough...
When Victoria Beckham smiles, the world smiles. Kind of. But do you love a VB grin as much as heatworld does? And who's got the best teeth in Hollywood? Let us know below...
