I have used Listerine Whitening products in the past. Listerine Whitening Mouth Wash promises have the same positive effects of regular Listerine (e.g., to fight plaque, gingivitis and kill germs that cause bad breath) plus a brighter and whitened smile.

Unfortunately, I have found many reviews/lawsuits recently that claim that the alcohols in Listerine cause a drying effect in the mouth (which is the burning sensation you feel which ultimately makes you want to spit sooner than later). Supposedly, people claim it is the drying power that naturally causes cells in the mouth to die, resulting in an increased probability of oral cancer.

Not sure what to make of these recent reviews but it definitely scared me off of any Listerine products for a while!
