Katy Perry brushes her teeth at least three times a day

Singer/songwriter Katy Perry has revealed that she is so scared of being accused of having bad breath that she brushes her teeth at least three times a day.

Perry, 25, who admits she was too poor to take her dental hygiene seriously when she was a child, also revealed that watching Britney Spears videos inspired her to brush her teeth religiously.

"I brush my teeth all the time. I wanted them to be, like, Britney Spears-white," the Daily Express quoted her as saying in a new YouTube.com interview. 

"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'.

"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, 'cos I'm gonna 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.
