When it comes to brushing our teeth, most of us do it automatically. Not Jessica Simpson. While promoting her upcoming show The Price of Beauty, Jess felt compelled to spill her no-so-fresh dental secrets to her online fans at iheartradio.com.

The outspoken beauty reveals that cleaning her chompers is not something she does on a regular basis. Ick!!! But thank the Lord, she IS a fan of Listerine!

Maybe that's why JS has got those boy issues. Just a thought.
