London, Aug 18 (IANS): Actress Julia Roberts, who is famed for her smile, says the best beauty advice she ever received was from her late grandfather and that was to brush her teeth with baking soda.
''I brush my teeth with baking soda. My grandfather would put a big heaping mound of it on his toothbrush. He had only one cavity in his entire life," contactmusic.com quoted the 44-year-old as saying.
Roberts, who is married to cameraman Danny Moder, says she doesn't really have any other beauty regime as she's too busy to spend lots of time on it.
''Sometimes that's all I do as far as a regimen goes. Look, I'm happy if I have on moisturiser and ChapStick! When you're dressing three people besides yourself, something has to fall away. I've learned to always have a big pair of dark sunglasses within arm's reach before going out," she added.
