You say calories, I say cavities

Carissa was brushing her teeth. She stopped, looked at me and said "I'm brushing really good so I don't have any calories in my mouth." "I think you mean cavities, Honey" I replied.
Then the next day, she was holding up a piece of candy and said "How many cavities in this?" I didn't have the heart to tell her that both calories & cavities would be correct!
