Emma Roberts, the niece of Julia Roberts, could be a candidate for invisible braces in future.
In an interview with Women's Health magazine, she drew attention to her "really crooked teeth", which she said she doesn't mind too much at the moment because they "give me character".
However, the Scream 4 performer added: "We Robertses have too many teeth for our mouths."
This could cause problems in the future when her wisdom teeth erupt, as it may act to push the other teeth further out of alignment.
Should this happen, Roberts' dentist may suggest invisible braces to realign them again.
Justin Bieber recently admitted in an interview with Rolling Stone magazine that he has been wearing invisible braces.
He explained that he had to have some teeth removed that were pointing inwards, but this created a gap that is now being closed with the aligners. He wears them every day apart from when he is eating and brushing.
