Katy Perry obsessed with teeth cleaning

Washington, Mar 23(ANI): Katy Perry brushes her teeth six times a day, as she is scared of getting cavities.

The 27-year-old singer always keeps 20 brand new toothbrushes with her.

"We won't go anywhere without a stack of brushes...When she was a kid she had 13 cavities. So she now brushes her teeth six times a day," Contactmusic quoted a source as telling the Daily Star newspaper.

The 'Firework' singer - has revealed that her tooth-cleaning obsession was inspired by Britney Spears.

"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'," she said.

"I'm really anal about that because I like good breath. A turn off for me with guys is, like, halitosis ... I'm the kind of friend that's like, 'Stick a piece of gum in your mouth, because I'm going to save some friendships for you.

"I'll brush my teeth after breakfast, lunch and dinner ... I did have 13 cavities at one time, so you can imagine why I'm so freaked out. When I was a kid I didn't really go to the dentist a lot ... and when I finally went, they were like, 'You might as well get a new set of teeth," she added. (ANI)
