Katy Perry has a serious obsession about brushing her teeth.







She confessed “I brush my teeth all the time. I wanted them to be like, Britney Spears white. I used to grow up seeing her music videos and be like ‘What does she do? Does she get a new set of teeth all the time? They’re so white!”







Katy reportedly always has 20 new toothbrushes around, and scrubs her pearly whites six times a day.








Why is she so obsessed with teeth? Katy explained “I did have 13 cavities at one time, so you can imagine why I’m so freaked out.”
