Katy Perry is obsessed with teeth cleaning

Celebrities and obsessions are almost synonymous and singer Katy Perry is no exception. As per reports she brushes six times a day because she is afraid of getting dental fillings.

This celebrated singer has 20 new toothbrushes.

"We won't go anywhere without a stack of brushes," a source has been quoted saying to showbizspy.com.

"When she was a kid she had 13 cavities. So she now brushes her teeth six times a day."

This celebrity singer has said that her tooth-cleaning habit 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 has been quoted as saying.

"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 said.
