London, July 23: Actress-model Helen Flanagan's obsession with brushing her teeth regularly has made her enamel sensitive.
The 22-year-old, who carries brush-paste wherever she goes, visited a dentist who advised her to just brush two or three times a day and use mouthwash in between, reports thesun.co.uk.
The "Coronation Street" star took to Twitter to share her grief.
"Just been to the dentist I dragged myself there. And because I'm obsessed with brushing my teeth it's made them too sensitive as I've attacked my enamel," read her tweet.
Even one of her friends spoke about her obsession and has called her paranoid.
"Helen is paranoid. She is always scrubbing away - sometimes up to 10 times a day. She was stunned to be told she's causing more harm than good," said the friend.
