Twilight hunk Robert Pattinson is so thorough in his dental regime, he once chipped a tooth flossing.
The British actor has developed a reputation for being scruffy and dirty after admitting he never washes his hair.
He previously said, "I don't have much of a sense of personal hygiene or styling or anything. I gave up washing it (his hair) a while back."
But his new Twilight co-star Bryce Dallas Howard reveals he's much more hygienic than he lets on - he was forced to book a dentist's appointment in 2009 after one vigorous flossing incident.
She tells New York magazine, "Actually, he's incredibly hygienic. He told me this story that made me crack up. He was like, 'Oh, I have to go to the dentist.' And I was like, 'Oh no, what happened? Just a check-up?' And he was like, 'No, I chipped a tooth.' And I was like, 'How?' And he was like, 'Flossing.'
"I don't even floss. So he's hygienic. Trust me."
